311 will host its sixth annual Summer Unity Tour later this year. Previous installments have seen the band pair with Matisyahu, The Roots, The Wailers, Snoop Dogg and The Offspring. This year the band has invited Sublime with Rome to join 311 on the road. Unity Tour 2011 kicks off in Bonner Springs, KS on July 8 and will hit amphitheaters through August 26, when it concludes in Seattle.

Sublime with Rome, features Sublime cofounders Bud Gaugh and Eric Wilson as well as new singer Rome Ramirez. For more on that group, check out the recent Relix feature on their efforts in the recording studio.
