The brothers launch the run in Portsmouth, VA, on Aug. 7, and work their way across country before wrapping up in Berkeley, CA, on Aug. 29.

Common [ tickets ], Toots and Maytals, Slightly Stoopid and Looner hold down the tour's opening slots. Additional special guests may appear on select dates, according to organizers.

According to a press release, the festival "takes its cue from Bob Marley, who through his inspired melodies, lyrics and soul, brought reggae music to a world-wide audience." Musical acts will encompass "a dynamic mix of reggae, hip-hop, ska, blues, alt/country, electronic and soul music."

Ziggy Marley [ tickets ], Bob's eldest son, has been singing, writing and producing with the Melody Makers--a group that also features siblings Stephen, Sharon and Cedella--since the age of 10. Last year, he released his solo debut, "Dragonfly."

This fall, Stephen Marley--who has sung, deejayed, written and produced for the Melody Makers--releases a solo album on Motown Records.

Julian Marley [ tickets ]--a self-taught musician who plays bass, drums and keyboards--issued his latest album, "Time & Place," last November.

Youngest brother Damian "Junior Gong" Marley issued a solo album titled "Halfway Tree" on Sept. 11, 2001. The set won a Grammy for Best Reggae Album.
