Devotees of Unity Gain refer to the Sunday-night climaxes of these 72-hour, multi-location marathons as "Church." And Unity Gain is worthy of worship. Since it started in the summer of 2000 as a mere club night at Boulder's Soma, the series has garnered a well-deserved reputation as the premier showcase for turntable talent in a non-commercial, underground setting. Typically, the sporadically scheduled parties span an entire weekend and move from ski towns along I-70 to Denver and Boulder and back again. Whatever the venue, Unity Gain promoters make it theirs, decorating with fabric, candles, tapestries, flowers and giant pillow installations. The custom light shows feature multiple film loops, 3-D screens and ambient projections. This sensual decor, combined with phenomenal music by local, national and international DJs, makes Unity Gain parties the bomb. Everyone's welcome, but there's no website, and no phone number to call. Keep an eye out for fliers in local dance clubs and record stores.
