talks about ghost beats and notes a lot.. I usually tune him out when he does, tho.. Just kidding..
About the only metal drummer I know that did conventional grip was Tommy Aldrich, who has played with everyone from Black Oak Arkansas to Whitesnake.. He, at least, used to play conventional, but may have eventually switched to matched - dunno, as I haven't seen him in a while.... Bad to the bone drummer, tho, no doubt about that..
Other than him, can't think of any metal drummers that do conventional..
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
