Prog heroes Yes have confirmed their first-ever festival, the Yestival. The full quadraphonic sound event will take place at Camden, NJ’s Susquehanna Bank Center on Saturday, August 3.

The event hosts will perform their 1971 classic The Yes Album and their 1972 release Close to the Edge in their entirety during the Yestival. They will also offer a mix of other material culled from throughout their career. Other confirmed acts include: The Musical Box, Renaissance featuring Anne Haslam and Carl Palmer’s ELP Legacy. Additional performers will be added to the event’s lineup in the coming weeks.

“This is a concept we’ve been trying to put into motion for some time, and only now we’ve been able to turn it into reality,” Yes bassist Chris Squire said in a statement. “We’re looking forward to starting Yestival out in the Philadelphia area, which has been a Yes stronghold since the ’70s.”

Exclusively licensed by Peter Gabriel and Genesis, The Musical Box reenacts Genesis’ early work. At the Yestival, the Genesis tribute at act will perform material from 1972’s Foxtrot as part of the album’s extended 40th anniversary celebration. Yestival will also boast a second stage featuring performances by up-and-coming progressive rock bands such as Scale The Summit and a special appearance by The School Of Rock. In addition, the festival will spotlight the art of Roger Dean, whose visuals and album covers for Yes, Uriah Heep and Asia have played an important part in progressive rock’shistory.
