The String Cheese Incident got some help from Sam Bush, The Leftover Salmon’s Andy Thorn and The Travelin’ McCourys’ Ronnie McCoury and Jason Carter for their Forecastle Incident show on the final day of the Forecastle Festival in Louisville, KY. The ten-piece band knocked out some classic bluegrass (and jazz) tunes over the course of the set, which many expected given the background of the guests involved. More surprisingly, the group also performed a few of the String Cheese Incident’s more electro-psychedelic tunes like “Rivertrance” and “BollyMunster.”

The set kicked off with the traditional tune “Blackberry Blossom,” which transitioned into a fantastic (and highly unconventional) “Rivertrance” before that song segued into Del McCoury’s “Quicksburg Rendezvous.” The middle of the set included a take on Bill Monroe’s “Blue Moon of Kentucky,” the eastern-influenced electro jam “BollyMunster” and a rare post-hiatus performance of “Stingray.” The show then wrapped up with Bill Monroe’s “Wheel Hoss” sandwiched between The Weather Report’s “Birdland.”

The String Cheese Incident will return to the stage July26 and 27 at the Red Rocks Amphitheatre in Morrison, CO.
