The old Phil Lesh and Friends, begun in 2000, was a step away from the gentle, cobwebby sound-world of the Grateful Dead, the band with which the bassist Mr. Lesh spent 30 years. It was loud and dense, full of Warren Haynes’s white-soul singing and red-meat Southern-rock guitar improvising. This new version keeps the solid rock rhythms; the drummer, John Molo, is the only carryover from that earlier group. But it’s a more delicate operation.
It focuses on the music that the Dead played in the 1970s, sometimes folk- and country-tinged. The current lineup includes Larry Campbell, from Bob Dylan’s touring band, on mandolin, fiddle and steel guitar; the chameleonic singer, guitarist and keyboardist Jackie Greene, whose voice suggests a compromise between the Grateful Dead’s two main singers, Jerry Garcia and Bob Weir; the keyboardist Steve Molitz; and the singer Teresa Williams.
