1981–1984

SIN 34 was named from the Los Angeles UHF television station Spanish International Network, channel 34. The band was established by vocalist Julie "Jules" Lanfeld and drummer Dave Markey, who met at a Middle Class show at the Starwood in West Hollywood. Realizing their common bond of punk rock and interest in bands like Black Flag and Devo, Dave and Julie decided to form their own. Agreeing that "SIN 34" would be a good name after Julie noticed it written in magic marker on Dave's backpack, Julie asked classmate Phil Newman to join on bass. The band initially rehearsed as a three piece until the introduction of Circle One guitarist Mike Vallejo. Vallejo played a few shows before returning to his main band, soon to be replaced by Chris Pedersen, who went on to star in the 1984 film Suburbia, and finally finding permanence with guitarist Mike Glass.^[4]

Sin 34 played shows opening for bands including Dead Kennedys, T.S.O.L., Social Distortion, Fear and Circle Jerks. Their first and earliest recordings were featured on the cassette compilations Meathouse and Charred Remains. In 1982 the band recorded their debut EP, Die Laughing, on Spinhead Records, ran by bassist Phil Newman, a self-produced and promoted record that quickly sold 1,500 copies. The band appeared on a series of local compilations such as Smoke 7's Sudden Death, Life Is Boring So Why Not Steal This Record on Nu Underground Records and the We Got Power: Party or Go Home LP. 1983 saw the band recording a full-length album, Do You Feel Safe, at Mystic Records, under the supervision of Circle Jerks guitarist Greg Hetson, again released by Spinhead Records. The album would sell 2,500 copies in its original pressing.^[5]

Sin 34 experienced local and national college radio airplay as well as receiving positive reviews in fanzines. In March 1983, Julie was featured in an article in Thrasher magazine highlighting her skateboarding abilities.^[6] The band continued to play shows as well as re-recording the song "12 Hour Trip" for Dave Markey's film Desperate Teenage Lovedolls.^[7] (The soundtrack originally released on Gasatanka Records in 1984, was re-issued by SST Records in 1987, re-released in an expanded edition CD by Sympathy for the Record Industry in 1997). Sin 34 was also among several bands released on Mystic Records' Mystic Sampler #1 along with Suicidal Tendencies, Ill Repute, Minutemen, Vox Pop and The Mentors. In September 1984, Sin 34 disbanded due to internal pressures, among other issues.
