The sixth annual Mountain Jam will return to Hunter, NY from June 4-6. Gov’t Mule will anchor the festival for the sixth year in a row, offering two full performances. In addition, the festival will feature: Michael Franti & Spearhead, the new Derek trucks & Susan Tedeschi Band, the Avett Brothers, Les Claypool, Yonder Mountain String Band, Toots and the Maytals, Matisyahu, Dark Star Orchestra, Traffic guitarist Dave Mason, ALO, Lettuce, Jonathan Tyler & The Morning Lights, Elmwood and the London Souls. Franti’s appearance is billed as his exclusive Northeast festival appearance, while Claypool will perform late night on one of the festival’s outdoor stages. Since he has performed with both the Allman Brothers Band and Gov’t Mule, Mason will likely collaborate with Warren Haynes during the weekend.
