Another round of artists has been added to the fourth annual Bonnaroo Music Festival. Recent additions include De La Soul, The Perceptionists featuring Mr. Lif, Akrobatik and DJ Fakts, and Peter Rowan and Crucial Reggae. Bonnaroo will also see a reunion performance by The Word, a supergroup featuring Robert Randolph, John Medeski and The North Mississippi Allstars’ Luther Dickinson, Cody Dickinson and Chris Chew. Originally formed at a Bowery Ballroom performance in 2001, The Word helped propel Randolph to fame before he released his first album, _ Live at the Wetlands _.
