For the second year in a row, the dates of the Bonnaroo music festival will coincide with the Country Music Association's biggest fan event of the year. Bonnaroo 2004 is set for June 11-13 on a 600-acre farm in Manchester, Tenn., located some 60 miles southwest of Nashville. The CMA Music Festival, a concert series previously billed as Fan Fair, takes place June 10-13 in downtown Nashville. Artist rosters have not been released for either event. Although Bonnaroo leans toward rock acts, the festival's 2003 lineup included Emmylou Harris, Lucinda Williams, Nickel Creek, Robinella & the CC String Band and Bela Fleck & the Flecktones.
