Who is Mazza L20?
Mazza L20 is a Liverpool‑born rapper and freestyle artist working in the UK drill scene, a style characterized by dark, trap‑style beats and often raw, narrative‑driven lyrics about street life and local communities. He is best known for his 2023 single “Murdaside,” which became a viral hit and pushed him into the UK Singles Chart’s Top 20, marking his first major breakthrough into mainstream British music.
Before his nationwide fame, Mazza L20 built a following by posting freestyles and short tracks on social‑media platforms, especially Instagram and YouTube, where UK drill artists often preview new material free of charge. His breakout year also saw the release of his sophomore full‑length project, originally titled Concrete Jungle (or similar charting long‑form release), which expanded on the themes of struggle and resilience in his earlier work. Today, he is widely regarded as one of the most electrifying new voices in UK rap, with a rapidly growing international profile.
Early life and background
Mazza L20 grew up in Liverpool, a city with a long history of working‑class communities, port culture, and a distinct local accent that shapes much of his flow and regional identity. Like many UK drill artists, he spent his teenage and early‑adult years navigating the same neighborhoods and environments that later became subject matter for his lyrics, giving his songs a strong sense of authenticity.
Public profiles and interviews describe his upbringing as marked by hardship, including periods of incarceration and brushes with the justice system, experiences he later channels into his freestyles and studio tracks. That background has helped position him as a “charva”‑style artist—raw, unfiltered, and closely tied to the streets rather than to a polished, commercial image.
Despite the challenges, he focused on developing his flow and writing, often recording on basic gear and sharing short clips online before gaining wider distribution through streaming services. Today, his roots in Liverpool’s L‑zone areas remain a core part of his brand, with fans often referencing the “L20” tag as a symbol of local pride.
How “Mazza L20” got his name
The stage name “Mazza L20” uses his nickname “Mazza” paired with the alphanumeric postcode “L20,” associated with certain districts of Liverpool. Postcodes are a common shorthand in UK rap and football culture, where fans and artists use them to show loyalty to specific neighborhoods or boroughs.
By tying his name to L20, Mazza emphasizes that he represents a particular part of Liverpool rather than the city as a whole, which helps him build a loyal local fanbase before expanding nationally and internationally. The name also works well visually on social‑media handles, merch, and album art, where “L20” appears as a compact yet instantly recognizable tag.
Musical style and influences
Mazza L20’s music sits firmly in the UK drill lane, using slow‑paced, minor‑key beats with skittering hi‑hats and deep 808s that create a tense, cinematic atmosphere. His flow is often “bouncy” and rhythmic, with a chanted, almost chant‑like delivery that makes his choruses easy to remember and sing along to.
Lyrically, he blends personal storytelling with broader social commentary, touching on poverty, violence, loyalty, and the pressures young people face in marginalized areas. His style draws from the wider UK drill tradition, which itself evolved from early Chicago‑style drill while adapting to British slang, accents, and lived experiences.
At the same time, Mazza incorporates elements of classic UK grime and road rap, giving his tracks a harder edge that appeals to both underground and mainstream listeners. This hybrid approach allows him to maintain underground credibility while still gathering large streaming numbers and chart placements.
Breakthrough with “Murdaside”
“Murdaside” is Mazza L20’s defining single, released in 2023 as a dark, emotionally charged track that quickly went viral on social‑media platforms and streaming services. The song’s title and hook reference a side of Liverpool life often kept out of the mainstream, tying the track to a very specific local context that resonates with fans from similar backgrounds.
Commercially, “Murdaside” reached the Top 20 of the UK Singles Chart and eventually earned gold (and in some cases gold or silver) certification, marking Mazza L20’s first major industry validation. The success of the track helped push his debut or sophomore album/project into the charts as well, turning his earlier underground buzz into sustained mainstream attention.
Music publications describe “Murdaside” as a “haunting tribute” to his hometown, blending somber production with stark imagery and confessional verses. For many listeners, the track works both as a street anthem and as a piece of social‑documentary‑style rap, capturing the emotional weight of everyday danger and loss.
How the track went viral
“Murdaside” first spread through short‑video platforms and YouTube clips, where fans and influencers shared the hook, dance moves, and reactions in short‑form content. UK‑drill tracks often perform well on TikTok, Instagram Reels, and YouTube Shorts because the repetitive, chant‑like hooks translate easily into memes and challenges.
From there, the track received playlist support on major streaming services and airplay on UK radio shows hosted by figures such as Kenny Allstar, who regularly feature up‑and‑coming drill and grime artists. Play‑listing choices by large platforms helped push the song’s daily‑stream numbers higher, which in turn attracted label interest and media coverage.
Mazza L20 albums and mixtapes
Beyond “Murdaside,” Mazza L20 has released a catalog of mixtapes and long‑form projects that trace his evolution from raw freestyler to polished, chart‑eligible artist. Early in his career he put out singles such as “Don’t Do It” and “White Plugs” in 2020, which were among his first widely distributed tracks and helped him build a foothold in the underground scene.
In 2021 he released an EP or mixtape titled Convicted Diaries (or similar prison‑themed project), which leaned heavily on personal experience and incarceration, using stark storytelling rather than just braggadocio. This project helped cement his reputation as an artist who can write introspective, vulnerable verses while still maintaining the hard edge expected in UK drill.
His 2023 breakthrough era coincided with the release of a full‑length album or strong‑performing project, often referred to in coverage as his sophomore set, which expanded on the sound and themes of “Murdaside.” Then in 2024 he followed up with the mixtape Against All Odds, which did particularly well in regional charts, including the Scottish Top 10, showing his reach beyond Liverpool.
Track‑by‑track highlights
When discussing Mazza L20’s discography, several tracks stand out as fan favorites and strong examples of his style. “Murdaside” remains the centerpiece, with its slow, ominous beat and haunting chorus that listeners often quote in everyday speech.
Songs from Convicted Diaries such as its title track or similarly named cuts dive into the emotional toll of jail time, family separation, and the difficulty of returning to normal life after release. These tracks feature more conversational flows and longer, narrative verses compared to the punchier hooks on his later chart singles.
On his 2024 mixtape Against All Odds, listeners hear a more polished, radio‑ready version of his drill sound, with stronger hooks and clearer song structures while still maintaining gritty lyrics. Cuts like “Against All Odds” or lead‑off singles often feature collaborations with other UK rappers, which broadens their appeal and helps cross‑pollinate audiences.
Collaborations and industry co‑signs
As Mazza L20’s profile has grown, he has worked with established UK rappers and producers, which has helped him gain credibility and exposure in different corners of the scene. Collaborations with artists such as Aitch, Potter Payper, and Loski place him alongside some of the most respected names in British rap, reinforcing his transition from underground freestyler to mainstream‑level act.
In addition to peer‑to‑peer features, he has received co‑signs from major figures such as Eminem, whose endorsement (often delivered via social‑media praise or shout‑outs) can significantly boost visibility for any UK artist. These co‑signs not only signal that his music is respected by veterans but also open doors to bigger festival bookings, label deals, and international touring opportunities.
Behind the scenes, production credits from established UK and US‑style producers help refine his sound, giving his tracks a more polished, radio‑friendly edge without sacrificing the raw energy that fans first connected with. The combination of strong features and high‑profile validation has turned his name into a regular talking point in interviews, magazine profiles, and industry‑focused roundtables.
Social media and fanbase growth
Mazza L20’s Instagram account, under the handle @mazza_l20, has hundreds of thousands of followers and serves as his primary hub for new content, behind‑the‑scenes clips, and local‑community messaging. The account often features short videos of him recording, on tour, or hanging with friends and family, which helps humanize him beyond the sometimes‑dark themes of his music.
He also maintains an active YouTube presence, with both official music‑video uploads and live‑session or freestyle videos, which are crucial for UK drill artists who rely on visual content to support their tracks. These videos not only drive views but also help algorithms surface his music to new listeners who discover him through suggestions and related‑video feeds.
Streaming‑platform profiles on Apple Music, Spotify, and Shazam list his catalog, tour dates, and official videos, giving long‑form fans a centralized place to dive deeper into his discography and upcoming shows. Over time, this multi‑platform presence has turned his once‑hyperlocal following into a national and increasingly international audience.
Managing public image and media
As his fame has increased, Mazza has appeared in major music magazines and digital outlets that profile rising UK drill artists, often framed as a “trailblazer” or “new guard” figure in the genre. These features tend to highlight his journey from freestyles in Liverpool to headlining arena shows, emphasizing resilience and determination.
He also balances this attention with periodic social‑media statements about loyalty, community, and the importance of staying grounded, which helps him maintain goodwill among his core fanbase. At the same time, interviewers and critics often grapple with the tension between his music’s violent imagery and the actual realities of his background, a discussion that shapes how he is perceived in the broader cultural conversation.
Live shows and tours
Mazza L20 has gone from small‑room rap cyphers and local club nights to selling out larger venues and arena‑style shows, including a headline performance in a Manchester arena in early 2024 or 2025. These shows typically feature a mix of his older underground tracks and newer chart‑ready singles, with a strong emphasis on crowd participation and call‑and‑response choruses.
Setlists at his headline gigs often open with one of his most popular hooks, such as “Murdaside,” to immediately engage the audience, then move into deeper cuts from his mixtapes and EPs before returning to a few high‑energy closing tracks. Supporting acts usually include other Liverpool‑based or North‑of‑England rappers, reinforcing local ties even as the tour expands to other regions.
Tickets for his shows are typically sold through major online‑ticketing platforms, sometimes with limited‑run merch bundles that include T‑shirts, phone cases, or vinyl or cassette versions of his latest project. For fans, attending a Mazza L20 concert is less about theatrical spectacle and more about raw energy, shared identity, and a chance to see a hometown hero perform on a much larger stage.
“Against All Odds” mixtape and 2024 success
Mazza L20’s 2024 mixtape Against All Odds is widely regarded as a turning point in his career, marking a more consistent, album‑style release that still fits within the fast‑paced world of UK drill. The mixtape’s title reflects the narrative of overcoming adversity—legal trouble, incarceration, and street violence—while still achieving creative and commercial success.
Lead singles from Against All Odds often appeared on streaming‑service playlists and radio playlists, helping the project chart strongly in the UK and parts of Europe. In Scotland, the mixtape achieved a Top 10 placement, a significant feat for a Liverpool‑based artist and a sign that his appeal is spreading beyond the North‑West.
Tracks on the mixtape showcase a more strategic approach to songwriting, with clearer hooks, tighter arrangements, and better‑balanced production across the board. At the same time, Mazza keeps his lyrics grounded in real‑life stories, ensuring that the project feels authentic rather than manufactured for chart success alone.
