Mesomorph Enduros is a various artists compilation album released in December 1992 by Big Cat Records. It was assembled by musician and composer J. G. Thirlwell, who had been asked by Big Cat to compile songs by his favorite underground American bands. The songs "Room 429", "Johnny Shiv" and "Blister" were recorded and made their debut specifically for the album's release. The album is dedicated to Unsane's former drummer Charlie Ondras, who had died in June.
