Shellac is an American group composed of Steve Albini (guitar and vocals), Bob Weston (bass guitar and vocals) and Todd Trainer (drums and vocals). Although they have been classified as noise rock, they describe themselves as a "minimalist rock trio". Shellac formed in Chicago, Illinois, in 1992 as an informal collaboration between guitarist Steve Albini and drummer Todd Trainer. Former Naked Raygun bassist Camilo Gonzalez sat in on early rehearsals and played on one song on Shellac's first singles before permanent bassist Bob Weston, formerly of Boston's Volcano Suns, joined. Shellac has a distinctive, minimalist sound based on unusual and urgent time signatures, repetitive heavy rhythms, an angular guitar sound, and Albini's surreal, bitingly sarcastic lyrics.
