I've been handed a lot of suggestions for metal bands to listen to and feed into my exploration of the music. Or in a few cases go back and listen to more closely if I remember them first time around.
Thanks to Gio, Mark, Rach and Tom for the following
Faith No More
Megadeth (the old stuff)
Obituary - Cause of Death
Prong - Beg To Differ/Cleansing
Slayer - Reign in Blood
Tool - all the albums (though I guess Lateralus is the big one?)
Trivium - Ascendancy
I was also lobbied to include hardcore - but it feels culturally and ideologically if not necessarily musically quite a different space from metal so I'm going to park it for now.
No Metallica, curiously.
