Two Grateful Dead principals and a host of hip-hop and DJ acts have been added to the lineup for the inaugural Bonnaroo festival, set for June 21-23 in Manchester, Tenn. Dead bassist Phil Lesh will be joined by his former bandmate Bob Weir for Phil Lesh & Friends' performance during the weekend, alongside other newly added acts such as Jurassic 5, Blackalicious, the Disco Biscuits, Corey Harris, Cut Chemist, Amon Tobin, and DJ Z-Trip.

A limited amount of additional tickets for the event, which is expected to draw more than 60,000 people, go on sale Saturday (May 18) via the festival's official Web site. The event will feature previously announced appearances from Phish's Trey Anastasio, Widespread Panic, Ben Harper, String Cheese Incident, Galactic, Gov't Mule, moe., Ween, Les Claypool's Frog Brigade, and Norah Jones, among many others. The full lineup is available at the Web site.

Manchester is located 60 miles southeast of Nashville, and is also within short driving distances of the Jack Daniels Distillery in Lynchburg and Wonder Cave in Pelham. "We're looking at creating a small city that will take care of people for three days the right way, and that takes a lot of money," festival promoter Jonathan Mayers of New Orleans-based Superfly recently told Billboard. "Music is the biggest element of Bonnaroo, but it's also about the camping, DJs, festival village, and lots of surprises."

He added that taping will be allowed at the festival, and plans also call for a documentary to be filmed of the debut Bonnaroo: "This is an important event, and we need to document it."
