tinyE: Interesting considering the Dave Mustaine formed Metallica. :P
Ulrich formed Metallica - he'd placed a posting in a local newspaper looking to put together a band as he had a track spot on a local demo.
Elmofongo: Which songs did you listen from Anthrax?
Madhouse, Caught in the Mosh, Among the Living?
Well Metallica does have a more accessible history I mean they are more well documented than Megadeth in some cases.
And the band starting from Kill Em' All to Black Album was quite the Metal Journay from playing in clubhouses to whole Arenas.
Too lazy to go browsing IMs, but one of the lads in our web development team showed me some of what he'd class as their better stuff before, and it didn't catch me enough to remember it. Prior to that, I'd heard the song "What Doesn't Die"on a Nuclear Blast compiliation album, which really caught my ear :D
To go off on a point - I think looking at Metallica, you can see what happens with a lot of metal bands on how they go "Mainstream".
I'll link this small clip:
