This is the record that I consider to be the rarest California ska record ever released.
I have been collecting rare California ska for decades and this is the one record that eluded me year after year. I don't know how many copies were made and there are still some rare California ska releases from the 80s that I don't have yet but I'm basing my criteria on internet presence and how many people I've met at record conventions (and elsewhere) that have actually heard of these records.
The Corvairs - Self Abuse 7" (1983)
A - Self Abuse
B - Never Stop Believin
They had an earlier release in 1981 that wasn't ska (but was still a great record):
The Corvairs - Took so Long 7" (1981)
A - Took so Long
B - Just a Friend
