NJ/East PA/South NY/North DE Club recommendations? Raves this summer? Good DYI concert venues?

Really wanna go out a bit more this summer and really really wanna check out a Y2K rave if any are going on. Usually I hung around Rutgers since all my friends were going there but now most are/have graduated and I really just wanna see more of the state and a bit of the neighboring states. Anyone got some recommendations?
