Backstage after the final show of a 2008 reunion tour, A Tribe Called Quest producer-rapper Q-Tip declares, "That's the last time we'll be on stage until we're in the Rock and Roll Hall of Fame."

Backstage after the final show of a 2008 reunion tour, A Tribe Called Quest producer-rapper Q-Tip declares, "That's the last time we'll be on stage until we're in the Rock and Roll Hall of Fame."

It sums up both the internal strife and the true importance of the seminal group profiled in Michael Rapaport's loving warts-and-all documentary, "Beats, Rhymes & Life."

Yes, there are hints of "Behind the Music" drama, particularly the fallout between Q-Tip and childhood friend and fellow Tribe MC Phife Dawg.

But it's the joyous rise of the jazz-sample-fueled brand of hip-hop personified by Tribe that set my head bobbing in the theater. It's a great hip-hop doc, and fans shouldn't miss it.
