Check out the article on this site, it has a review of a recent show.
The first gig i ever went to was largely a white crowd, the blacks were countable, but that was because there was no awareness among the black fans that there was a local rock scene, but now there's more black fans and band members than white, with just one band which has all white members and im afraid they're gonna phase out coz of being the minority which shouldn't be right. the problem then becomes how can we intergrate the white fans back into the scene. other wise right now it's a black rock scene, as for the metal scene, its mainly male, i've just met two females who listen to metal, and when the guys realize that, it amazes them, at which point i wonder why. hope that answers the question somehow.
