Dream Theater are hit and miss. Black Clouds was one of their best but I didn't dig ADTOE EDIT: Just re-listened to ADTOE, it's better than my original impression.
Gojira (although From Mars to Sirius is still my favourite album by them, and maybe from Metal in General) Periphery System of a Down (not the albums, the live shows) Lamb of God Scale the Summit (can't fucking wait for the new album) Disturbed, I really liked their latest albums
