Prince is back. Wasn't that Prince scorching up the stage with Beyonce in the opening number for the Grammys? Didn't Prince just appear on--of all things!--The Ellen DeGeneres Show earlier this month? He's even on tour for the first time in seven years, and last Monday, in a PR stunt last attempted by David Bowie, Prince broadcast his Los Angeles concert live to 32 movie theaters across the country, giving attendants a copy of his new album Musicology. Earlier that day, he announced the kick-off of his own music downloading store, www.npgmusicclub.com, from which he will sell several of his songs and albums and offer exclusives to fans who pay the $25 membership fee. This Monday, he will be inducted into the Rock and Roll Hall of Fame. It's like the little man stored up a decade of work just to blow it in a month. Whatever the reason, it's a welcome return. This Friday, it's time to pay the man back: Start shakin' that ass, shakin' that ass.
