David Grubbs (born September 21, 1967), guitarist, pianist, and vocalist, was a founding member of Squirrel Bait, Bastro, and Gastr Del Sol. He has also played in Bitch Magnet, The Red Krayola and The Wingdale Community Singers. Squirrel Bait was a 1980s Louisville, Kentucky punk rock group that released a 12" EP and an album on Homestead Records. Grubbs's next group was Bastro, which released two albums on Homestead. In 1991 Bastro morphed into the more avant-garde Gastr del Sol. This project soon became essentially a partnership between Grubbs and Jim O'Rourke.
