In case the lava lamps and disco balls don't tip you off, the '70s are back at 8TRAX. Slip on your bell-bottoms, strap on your platform shoes, and groove to Chic, the Village People, or Donna Summer on disk. After a while, it might seem like you're in your own Quentin Tarantino film. Swing by on Thursdays when the calendar fast-forwards to the 1980s to celebrate the music of that not-so-long-gone era.
