Yeah, I hope they quit whatever they're doing. Society is pretty bad without hip-hop brining it down further.
However, which band of today will be influential in the future? Hard to say, there's a few I'm leaning towarRAB, but I won't say anything at this point in time.
I don't agree with the Pantera statement however, they were great, but they are not exactly recent, are they? They were pretty much dead when Anselmo left the band to play with Necrophagia, Viking Crown, Down, and then Superjoint Ritual. With the death of Dimebag and the dissolution of Damageplan, there is no more chance for Pantera to do anymore than it already has. However, I am willing to admit that Pantera has had a lot of influence already, considering the huge amount of side projects that it's former band mates had done.
EDIT: We need another Sex Pistols style band, now there is a band that influenced a generation.
