Little Feat co-founder Bill Payne has joined the lineup of this year's Mountain Jam Festival, bolstering a roster that already included Gov't Mule, Black Keys and Robert Plant.

Payne, who joined the ranks of Leftover Salmon on the band's most recent tour, will play in a trio with multi-instrumentalist Larry Campbell and singer Teresa Williams, part of a Sunday bill that includes up-and-comers Hurray for the Riff Raff and Alabama Shakes.

Since making his mark as an original member of the Little Feat lineup in 1969, Payne has remained one of the band's main musical anchors, helping chart its rise to fame in the '70s, adding to the spark for an unlikely reunion in the '80s, and spending countless hours in the studio and on the road along the way. In addition to his long-standing Little Feat gig, Payne has pursued solo careers as a musician and photographer, and his heavy touring schedule — which has made room for previous gigs with Campbell and Williams — includes a one-man music, photography and Q&A show dubbed "Tracing Footsteps."

Payne's addition comes in the waning days of availability for Pretty Early Tickets to this year's Mountain Jam, and shortly before single-day passes to the festival are put on sale to the public. Prices are scheduled to go up on April 8 at midnight, so don't delay — visit the Mountain Jam site to take a look at complete lineup information and purchase your tickets today.
