CommonThis year’s Rock The Bells Festival Series is getting bigger and bigger by the week.

Guerilla Union, the organizers behind the annual event, announced this week that they’ve just added Common, DOOM, Killah Priest, and Boy Jones to the line-up.

The festival will head to four major North American markets this summer, kicking off on August 20 in Los Angeles.

It will also feature seminal hip-hop artists performing their classic albums, a tradition the festival started last year — Nas, Lauryn Hill, and Cypress Hill are among those confirmed to perform full album sets.

New line-up addition Common will perform his Kanye West-produced 2005 breakthrough album, Be, in select markets; and Wu-Tang Clan associate Killah Priest will perform 1998 release, Heavy Mental. Previously announced co-headliner Erykah Badu will also perform her debut album, Baduizm.

British rapper DOOM will take the stage making his North American festival debut. Joining him for all four dates is Boy Jones, the son of late Wu-Tang member Ol’ Dirty Bastard, who will be co-hosting the 36 Chambers Stage.

This year’s festival will feature four stages — the Rock The Bells Stage, the Paid Dues Stage (featuring indie acts), the new RZA-curated 36 Chambers Stage (primarily featuring members of the Wu-Tang Clan), and the Grindtime Now Stage (featuring battle-style performances).

Pre-sale for the New York show starts Thursday (June 9), and general on-sale starts June 11. The Boston show pre-sale starts June 16, and general on-sale starts June 18. West Coast dates are currently available for purchase.
