Indie rock band from Chicago, IL, USA, formed in 1992 by vocalist/guitarist Steve Albini and drummer Todd Trainer. Former Naked Raygun bassist Camilo Gonzalez sat in on the band's first few rehearsals and recorded one song ("Rambler Song") with them before Bob Weston ed to permanently fill the bass position.

Their music have been classified as post-hardcore, noise rock and math rock, but Shellac described themselves as a "minimalist rock trio".

Shellac recorded and performed infrequently due to their geographic separation (Albini lived in Chicago, as does Weston; Trainer lives in Minnesota) and the fact that all the had day jobs (Albini was a recording engineer, as is Weston; Trainer managed a warehouse and tended bar).
