Knot Feeder was a math rock band from Pittsburgh featuring ex-members of Don Caballero, Tabula Rasa, and Southpaw. The band consisted of guitarist Mike Banfield (ex-Don Caballero), drummer Rob Spagiare (ex-Tabula Rasa), guitarist Andrew Grossmann (ex-Tabula), and bassist Andy Curl (ex-Southpaw). They recorded a CD with J. Robbins in 2007, which was released on January 24, 2009 at The Smiling Moose.

Guitarist Mike Banfield left Don Caballero, which he helped co-found with Damon Che, after their 1999 European tour supporting "What Burns Never Returns," their third release on the Touch & Go label, because he did not want to quit his job in Pittsburgh and relocate to Chicago. Damon Che continued to play with Don Cab, and the other guitarist Ian Williams went on to form the band Battles (band). After departing Don Cab, Banfield hibernated until a member of Pittsburgh band Mihaly connected him with drummer Rob Spagiare of the post-hardcore band Tabula Rasa. "We played a few times and it never materialized into anything, but then I got inspired and wanted to play more seriously. So I called Rob, and he brought along guitarist Andrew Grossmann (ex-Tabula)." Soon, friend and promoter/sound engineer Sean Cho hooked the trio up with bassist Andy Curl, whose previous band, Southpaw, was known for its complex extended jams. And thus Knot Feeder was formed in 2006.
