UPDATE 7/11/13: Rock the Bells has just announced a few more performers for select stops. Please welcome Big Sean (in Washington, DC and New York), A-Trak (in LA and DC), Chief Keef (LA, DC, San Francisco and New York) and IAMSU (LA and San Francisco). Great additions! We now return you to your previously published line-up announcement...

One month after pioneering hip hop festival Rock the Bells announced that Wu-Tang Clan and Bone Thugs-N-Harmony would bring out Ol Dirty Bastard and Eazy-E holograms, respectively, organizers announced a second round of additions, including real-life rappers J. Cole, walking quotable Riff Raff and tongue-twisting Queens rapper Action Bronson.

Veteran rappers Slick Rick, Doug E. Fresh and KRS-One, joining an already formidable roster that includes Talib Kweli, Kid Cudi, Black Hippy, Common and Jurassic 5, among many others. While still primarily a hip hop festival, this year's outing also boasts some impressive EDM artists, including genre-blind mash-up king Girl Talk and Colorado electronic artist Pretty Lights.

The festival, now celebrating its 10th year, is set to rock four cities this year: Los Angeles (Sept. 7-8), San Francisco (Sept. 14-15), Washington D.C. (Sept. 28-29) and New York (Oct. 4-5).

Last month, Chang Weisberg, the man behind the festival, told Fuse how the holograms came to be and that there was a possibility of even more holograms, including Biggie and Big Pun.

Here’s a complete list of who will be rocking which stage this fall:

Girl Talk (all markets)

Pretty Lights (NY)

J. Cole (LA, DC, NY)

Slick Rick and Doug E. Fresh (all markets)

KRS-One (all markets)

Riff Raff (all markets)

Action Bronson (LA, SF)

We spoke to Action Bronson and Kendrick Lamar about the significance of the festival and why they're excited to perform at Rock the Bells.
