One of Cali's most recognized festivals is back again. Guerilla Nation is prepping Rock The Bells IV for August 5, and this year's headliner is the legendary hip-hop group Wu-Tang Clan.

Two years ago, the entire hip-hop group Wu Tang line-up (including ODB) performed before a crowd of around 8,000 and has since become a legendary show. This year, the Wu will headline the event, but their performance will feature a special tribute to the late member of the hip-hop crew – ODB.

The festival, which once again takes place at San Bernardino, California's NOS Events Center, will also include a line-up of legendary members of hip-hop culture consisting of hip-hop and rap artists Mos Def, Taib Kweli, Redman, De La Soul, Aesop Rock, Living Legends, DEL The Funky Homosapien, Immortal Technique, MURS 3:16, Visionaries, Self Scientific and Planet Asia, among others to be announced at a later time.

"This year's show will be the greatest gathering of lyricists I can imagine," says festival founder and organizer, Chang Weisberg. "Rock The Bells has become the ultimate platform of integrity for conscious, hardcore, and independent music. And we are excited for the fans who have made this their annual destination year after year. I can honestly say that our fans will witness something that will never happen again...this year's surprise performances will be talked about for many years to come."

Yes, Rock The Bells will feature surprise live performances like past festivals. Also, Supernatural will be attempting to break The Guinness Book of World Records record for Longest Freestyle Rap of 8 hours and 45 minutes currently held by Canadian rapper, D.O.

Tickets for the event go out sale on May 20.

An additional show in Northern California has also confirmed for Sunday, August 6 with details to follow at a later date. And the event plans to hit the road after its California festival run and tour clubs all across North America this fall with plans for Europe and Japan in the winter.
