Atheist - Piece of Time - my favourite album of their's and one of the few albums I think is underappreciated by the metal community.
Cancer - Death Shall Rise - Got the new reissue to replace my 2nd hand copy which had CD "rot". Now if only Noise reissued Skyclad's Prince of the Poverty Line, I'd be a happy little pig!
And there's always one song from new Iron Maiden that burrows deep inside my head. And invariably it's the work of Adrian Smith who has an amazing knack for memorable hooks and melodies.
Keen to check this out - only heard their later more cross over thrash stuff.
