Rock the Bells

Rock the Bells was an annual hip-hop festival that originally took place in Southern California only, but has since toured throughout the world. The concert featured a line-up of high-profile alternative hip-hop artists, often headlined by a more mainstream artist. The first festival was held in 2004, featuring a re-united Wu-Tang Clan, who performed four months before Ol' Dirty Bastard's death. That festival is covered in depth by a documentary film also called "Rock the Bells".
Club Tour.
The concept was taken from the original, highly successful annual West-Coast hip-hop festival and transformed into a full-fledged United States tour.
2007 Festival Series.
Rock the Bells 2007 had 3 major venues scheduled; July 28 and July 29 in New York, August 11 in San Bernardino, and August 18 in San Francisco. These select shows were headlined by a reunited Rage Against the Machine, and co-headlined by Wu-Tang Clan. The artists appearing in the shows appeared in rotating slots over the two-show weekend in New York, and selected performances for the remaining duration of the 20 shows, which were head-lined by the Wu-Tang Clan. Five cities also had a second stage called the Paid Dues Independent Hip Hop Stage. Rage Against the Machine was the festival's first non-hip hop act to be featured.
 
New York City Dates.
In July 2007, the Rock the Bells festival came to New York City, and this event became particularly noteworthy. Upon selling out the massive Randall's Island venue very quickly, the one-day stop in NYC was expanded to two days, and a number of new and exclusive guests were added to the bills. The festival included the full Paid Dues festival lineup performing on a second stage, reunited headliners Rage Against the Machine and Wu-Tang Clan, guest appearances during the show (including Scott Ian performing Bring the Noise with Public Enemy), a special performance of Black Star from Mos Def and Talib Kweli and one of the near-final performances of noted hip-hop luminary Pimp C.
2008 Festival Series.
2008 also marks the first year that Rock the Bells went global with four stops in Europe and one in Japan. Highlights of the series include a first time date in Toronto, plus a return to the Glen Helen Pavilion in San Bernardino where last year's show sold out with a capacity crowd of 45,000 people.
