The String Cheese Incident have announced the guests for their “Forecastle Incident,” which will take place on Sunday, July 14 at the Forecastle Festival’s Boom Stage. The band will be joined by Sam Bush, Andy Thorn of Leftover Salmon and Ronnie McCoury and Jason Carter of The Travelin’ McCoury’s.

The theme for the performance will be “Bluegrass & Beyond.” If the guests didn’t already suggest it, the band is promising an instrumental extravaganza that will be a “raucous exploration of all that bluegrass was, is, and is becoming!”

The String Cheese Incident will also be involved in two more performances associated with the festival. The band will close out the Main Stage on Friday, July 12, and they will also play a late-night gig at the Palace Theatre in Louisville on Saturday, July 13.

Tickets to the Forecastle Festival are still on sale for $180.
