I feel like hardcore is very much a genre where you either sink or swim. You either become a legend or you fade rapidly into obscurity. If you can't keep topping yourself, you're ousted quickly by even younger kids than yourself. Hardcore is one of the few careers where you can be washed up by your mid-20s.
So who's in and who's out? Who's making waves and who's on the decline? Quite frankly, that would take too long to list, and I'd probably be wrong. However, I can give you some ideas on who the most valuable players in today's scene are, and who you might be looking at to headline Chaos in Tejas by next summer.
