Got a few more updates for the upcoming Rock The Bells Festival dates, and an addition to one of the stops.

The line-up of performers for this year's tour features Nas & Damian "Jr. Gong" Marley, The Roots, Big Boi, Busta Rhymes plus many more. But during the eagerly-awaited L.A.-area stop, there will be a special guest.

The guest specific to this Los Angeles show is the addition of Ice Cube, the legendary rapper and N.W.A. founder, marking his first ever appearance on the Rock the Bells stage.

"Ice Cube is true legend," said Chang Weisberg of Guerilla Union, the Rock the Bells organizer. "Having this icon perform on Rock the Bells, especially in his hometown, is a true honor for me and will certainly be an unforgettable experience for LA fans."
