Yes, there is a plot, sort of, and personal stories told à la A Chorus Line about how these individuals came to, and sometimes were salvaged by, dance. But ultimately what makes this 90-minute event compelling are the on-stage moves, a swirl of hip-hop, free style and other street genres. Bradley “Shooz” Rapier conceived the idea for the show, and the dozen-plus cast members — collectively known as the Groovaloos — assembled and intermittently improvised the choreography. The original version premiered in 2005 at Burbank’s Falcon Theater and sold out a 10-week run. Most reviewers found the fact-based stories moving and artfully woven into high-energy, dance-drenched performances. The creative team and dancers workshopped this baby over the following year and returned for another sold-out run in 2007, this time at the larger Luckman Performing Arts Center at Cal State L.A. The cast now heads south for a two-week run that promises more dazzling moves. To see video clips of Groovaloo on Dance Channel TV, go to www.laweekly.com/stage and click on the dance pick.
