The Chop Tops were a rockabilly trio from Santa Cruz, California consisting of Sinner (vocals/standing drums), Shelby (guitar), and Josh (upright bass). The band was formed by Sinner in 1995, Shelby joined in 1999, and Josh took over bass duties in 2014. The band coined the phrase "Revved-Up Rockabilly" to describe their wild, upbeat blend of rockabilly, psychobilly, old punk, teddy boy, and surf music genres. The Chop Tops headlined their own national tours, toured with bands like Mad Sin and the Nekromantix, and opened for many bands including the Dead Kennedys, Suicidal Tendencies, Dick Dale, John Lee Hooker, and Chuck Berry.
