It's called Making Music with Carter Beauford and Victor Wooten. Netflix has it. At the end of the Special Features section Vic does a bass solo that is unreal. He de-tunes his bass and starts slapping the thing around, then re-tunes it without the audience noticing, and keeps playing.

Truly amazing. His playing is very inspiring, check this DVD out!
PS, Am sure this thread is redundant, however I could not find another mention of it via the search function
