Diamond Head, hands down. I'm a HUGE Diamond Head fan of both the original and current lineup so watch out
I'm only just recently FINALLY getting around to getting into Iron Maiden who I really should have been into all along. I need to hurry up with the crash course because I've got a ticket to see them next month!
Saxon that's another band/album I've been meaning to get around to but still haven't ... yet.
I have the Angel Witch record ... it's good but by comparison to the other three albums not nearly as outstanding. So far they've struck me as being "the best of the rest".
