For Thylacine:
Deep Wound - EP It's the 80's, and hardcore is just getting going. Deep Wound is one of the first bands to play hardcore really fast. They put out a 7". It's way good. Members went on to be in Dinosaur Jr.
Crestfallen - Streaks of Terror From Virginia. Music that is remniscent of what was going on in Virginia at the time. Sound a bit like pg.99, I guess. Totally awesome. Totally punk. Lots of screaming and dischordance. Possibly screamo.
(the) Melvins - (a) Senile Animal Really, this should need no explanation. It's the Melvins. They went into the studio with Big Business and this is what came out. It's slow, it's heavy, it's loud. Two drummers. Two bassists. One Buzz.
