LOVE April Wine, btw. Easily one of my all-time personal faves.
Anyhoo... in the
Punk category... Suicidal Tendencies'
Lights... Camera... Revolution!
Some feel that by the time they released this album, they had crossed over from hardcore punk to thrash metal. The lines have always been pretty blurred to me, though. I could have picked a much earlier album (they were all very good), but this one is my favourite.
