From wikipedia:
Crain was an indie band from the late 80s and early 90s from Louisville, Kentucky. The band was similar to Slint and Rodan, as a part of the math rock and post-rock genres. They were formed after the demise of the Louisville band, Cerebellum.

Crain released two full-length albums and a handful of 7" records. Their first record, that Steve Albini produced, Speed was an early blueprint for releases that would follow in the post-rock and math rock movements. The lineup at that time included Jon Cook (bass, vocals), Joey Mudd (guitar, lead vocals), Tim Furnish (guitar, vocals on "King Octane") and Will Chatham (drums). The songs from Speed were written by Cook, Mudd and Furnish.
