To very liberally paraphrase Gen. Douglas MacArthur, old ravers don't die, they just start going to better clubs. Eleven50's stairway entrance on Crescent Avenue is a symbolic ascent from the raver underground. Like underground raves, eleven50 is a big building with loud music, disorienting lights and partying people. But eleven50 replaces the glow sticks with Gucci and the endless lineups of faceless DJs with a high caliber of internationally recognized spinners. And go figure -- eleven50's cover charge is cheaper than most underground raves.
