Anyone who was old enough to experience the first round of rave culture and still young enough to give a damn, do you remember PLUR? You know: Peace, Love, Unity, and Respect? That was the motto behind raves when they first started, before the atrocious morph into the disgusting, cooler-than-thou mentality that now occupies clubs from South Beach to Los Angeles. When raves moved to a professional atmosphere, it was only a matter of time before the moneyed few distorted everything. Thanks, guys. But a few places still hang on to the good-vibe mode of thought, and Lumonics is one of them. Each weekend, for about $12 to $15, a spectacular light-and-sound show is followed by a dance party with some of the finest DJs around today. It's sort of like being at Level, only without all the jerks.
