Most of the videos that I've seen of the LA auditions for America's Best Dance Crew Season 4 present dancers doing styles that are very close to traditional hip hop or bboying. There are few cowboys, tapdancers, or other 'outside' styles.
Here's one notable exception: No Label from Los Angeles, CA. This is one graceful and lyrical audition incorporating ballet and interpretive dance. It's difficult to say if they are ABDC material without seeing their choreography callback, but their audition stands out.
