Q Tip of A Tribe Called Quest live in concert.
Rap music might seem like a young person's game. But hip hop is old enough now to have its own golden age. The era was dominated by acts including Queen Latifah, Public Enemy... and A Tribe Called Quest. The Queens, New York quartet formed as a crew of high school friends. For almost a decade, Tribe's message-oriented music sliced through hip hop's early 90s gangster bravado. "Beats, Rhymes, and Life: the Travels of A Tribe Called Quest" is a new documentary that opens today in Los Angeles. It depicts the group's rise and captures its bitter break up. Christopher Johnson reports.
