I was digging through some old tapes and I found this Graveyard Rodeo live set recorded off of WTUL's "TUL Box"(they would broadcast live every week either at Tipitinas or Muddy Waters, and it was usually some crappy college rock, but once in awhile they'd have somethin' heavy.) Nuclear Crucifixon played this show too, but I lost that tape a long time ago while moving. Bummer.
While transferring this to mp3, the tape broke during the last song of the set.
This isn't a very good quality recording, and the soundguy had a weird effect on Perry's vocals, but here it is. It's about 22 minutes long.
