IMO , Metallica's best album ever KillemAll
I think Ride The Lightning betters it, but it all went gradually downhill from there :)
I think Reign In Blood has never been topped and sounds as fresh as it dis back then and of course Priest are awesome!
Couple of favourites for me -
Motorhead Ace Of Spades just such a dirty, sleazy rock and roll lp that helped pave the way for thrash.
The first L.A. Guns record - sure Guns N' Roses 'Appetite for Destruction' is a classic and I've always got love for the big hitters like Crue but these guys should have been way bigger than they were. Pretty punky and sleazy.
I loved hardcore punk and I love thrash but I could never get into Crossover, but a gem I go back to year after year is
Suicidal's 'How Will I Laugh Tomorrow...'. Think it bridged their change in style really well before it all went wrong a couple of records later
