The Syrenz auditioned for America's Best Dance Crew Season 4 in Los Angeles. For those who have been asking, they're the crew with the fans shown prominently on the MTV trailer for ABDC4.
Though we don't think there's any non-MTV tape of the audition, Teldon identified two videos of The Syrenz' audition routine: their rehearsal the night before the auditions and this polished version of the same routine (both from TheSyrenz Youtube channel). They show an blending of sensual (but not hoochie) choreography and hip hop technique that feels different than most other crews I've seen. Here's an interview with them from Pacific Rim Video. Thanks, Teldon!
