I was never a metalhead, always more of a ska/punk kid with some locale based ghetto influences... but growing up all my best friends were, and I ended up engaged to one. It's had a slight influence over time.
Some of my favorite metal fusions over the years. (Definitely not for the purists)
Steel Panther
Skindred
Pitchshifter
H-BlockX (also one of the first metal bands I was ever exposed too, later got to work on 2 records and this music vid with them.)
Guano Apes
Nonpoint
(hed) p.e.
Anthrax feat. Public Enemy
Chevelle
Less fusion... more semi-precious ore related grit I've been dragged and beaten into eventually loving.
Fear Factory
Snot
Texas Hippie Coalition
