There are no unreleased Botch or These Arms Are Snakes songs as far as I can recall. Roy had a 7″ single for “Reno, I’m Coming Home” that was supposed to come out on a record label run by Sean Carlson but then he got too caught up in building Fuck Yeah Fest and being a total creep to women so it never saw the light of day. There were two unreleased songs on that.
Russian Circles has a few unreleased songs, but they’re interlude/ballad type songs that just felt unnecessary on the albums. It’s doubtful they’ll ever see the light of day.
