Hey Rosk, see you're enjoying yourself!
I have something for ya...
I found all 4 Death demos, plus a bunch of other stuff (I'll put in the tape a bit of extras, like the Massacre demos, and a Slaughter rehearsal with Evil Chuck).
I'll also send you my favorite demo of all time: Legacy - Burnt Offerings (I probably don't need to tell you this, but Legacy is Testament with Zetro singing - before he left to join Exodus and Chuck Billy stepped in).
Give me 3/4 days, because I doubt I'll have any time to get the tape done before Saturday, but in the meantime you can send me your address.
Goes without saying that the sound quality is not that great...but this stuff is really brutal, I think you'll enjoy it!
