Nas, Damian Marley, the Roots, Big Boi and Common, among others, will lead this summer's Rock the Bells traveling hip-hop festival, which is set to visit 10 North American cities on consecutive weekends from June 27-Aug. 9.

Also on the bill in various markets are KRS-One, House of Pain, Reflection Eternal, Tech N9ne, Murs, RZA, Supernatural, Raekwon, Sage Francis, Pete Rock and others. Each tour stop will feature 25 artists on two stages.
