If anybody knows their way around a festival, it’s Trombone Shorty. Born Troy Andrews, he got his start (and nickname) earlier than most: at four, he made his first appearance at Jazz Fest performing with Bo Diddley; at six, he was leading his own brass band; and by his teenage years, he was hired by Lenny Kravitz to join the band he assembled for his Electric Church World Tour. Shorty’s proven he’s more than just a horn player, though. Catch a gig, open the pages of the New York Times or Vanity Fair, flip on any late-night TV show and you’ll see an undeniable star with utterly magnetic charisma, a natural born showman who can command an audience with the best of them.
