After only one year with the Blue Grass Boys, Greene joined the Jim Kweskin Jug Band -- which also included Keith plus Geoff and Maria Muldaur -- and played on that band's 1968 album Garden of Joy. Not content to stay in one place, he split for California after one year and joined the Blues Project, which then evolved into Seatrain. Greene stayed for over three years, playing on the band's self-titled 1969 album for AM, another self-titled LP for Capitol two years later, and 1972's Marblehead Messenger. With Eric Weissberg, Jim Rooney, and old friend Keith, he then formed the Blue Velvet Band, which recorded only one album, Sweet Moments. Greene spent the rest of the '70s playing with James Taylor, Emmylou Harris, Rod Stewart, Muleskinner, Taj Mahal, David Grisman, and Loggins Messina, in addition to recording three albums as a solo act with his backing band, the Zone. The first two, Duets (1977) and Ramblin' (1979), appeared on Rounder, while 1980's Blue Rondo was released on the Sierra label. An early-'80s tour of Japan with Tony Trischka and Peter Rowan was documented on the Japanese Nippon label by Bluegrass Album and Hiroshima Mon-Amour (both 1980). ~ John Bush, Rovi
