Peter Rowan is a bluegrass master. His musical roots go back to Bill Monroe. He didn’t just hear Bill Monroe’s recordings – he played guitar and sang lead with Bill Monroe and the Bluegrass Boys in the mid-1960s. After stints in Earth Opera, Muleskinner, and the Marin County rock group Seatrain, he co-founded Old and in the Way with Jerry Garcia and David Grisman. Since then, he’s recorded more than 30 albums and earned six Grammy nominations and a Grammy. His classic originals include “Panama Red,” “Lonesome L.A. Cowboy,” and “Moonlight Midnight” – and he’s just released a new album, Twang An’ Groove Vol. 1, featuring high-energy live versions of traditional classics and some of Peter’s outstanding originals. “The entire band coalesces around a supple groove, suggesting a sound not unlike the Grateful Dead in full jam band motif,” says the website Country Standard Time, adding that the free form improvisation “all sounds in sync, a reflection of the band's competence and confidence.” Joining Peter tonight will be Ramblin’ Jack Elliott, Nina Gerber, Blaine Sprouse, Mike Witcher, and Jeff Keana'aina. Get your tickets early – this should be a glorious musical celebration, led by a true master!
