Actor Michael Rapaport ("Boston Public," "Prison Break") directs this documentary about influential NYC hip-hoppers A Tribe Called Quest. The film--shot straight from a fan's viewpoint--certainly lauds the band's heady innovation but doesn't gloss over the ongoing acrimony between members Q-Tip and Phife Dawg. Rapaport's camera has an all-access pass to the group's 2008 reunion tour, and it captures some telling backstage moments. Interviews with assorted rap and hip-hop luminaries (Mary J. Blige, Mike D, Common, Mos Def, De La Soul, Ludacris) put it all in perspective. 97 minutes R.
