This Happened: Sir Mix-A-Lot Performed "Baby Got Back" With an Orchestra

Sir Mix-A-Lot's "Baby Got Back" got the full-orchestra treatment on Friday, and the 50-year-old artist was joined on stage by a bunch of very, very excited women who showed off their best dance moves. The performance was part of the Seattle Symphony's Sonic Evolution project at Benaroya Hall. This year, composer Gabriel Prokofiev switched things up by orchestrating the popular '90s song with Sir Mix-A-Lot, a Seattle native. As the song started up, Sir Mix-A-Lot invited women to join him on stage, and they all got really into it — especially one woman, who stood out as the true star of the night as she busted a move front and center.
