When Prince comes to the Montreux Jazz Festival, all bets are off. On his third visit to the Swiss Riviera for the 47th edition of the event, he was given carte blanche over three consecutive, sold-out evenings and appeared determined to cover as many bases as possible. The first concert saw the purple yoda attack new material and old classics. A spur of the moment performer who can turn on a dime, literally and metaphorically, he covered James Brown, Curtis Mayfield, Aretha Franklin and Chaka Khan before delivering an unscheduled second encore of "Purple Rain" in honor of the late Claude Nobs.
