It’s rare enough when Jerry Miller and Terry Haggerty do shows of their own, so their teaming up for tonight’s concert is especially delicious. They came to attention in two of the most acclaimed ’60s San Francisco rock bands: Miller is a founding singer and lead guitarist of Moby Grape, and Haggerty is the iconoclastic guitar innovator from the Sons of Champlin. The band features veterans of Bay Area rock groups who have played with Miller for more than 30 years. The new ingredient is the recent addition of Haggerty, and sparks fly when he and Miller launch into their guitar jams. In addition to updated rock and blues classics such as “44 Blues” and “Lucille,” the band tackles tunes from the Moby Grape catalog including “Hey Grandma,” “8:05,” and “Naked If I Want To.”

Jerry Miller may be known for his guitar chops (he’s number 68 in Rolling Stone’s 100 Greatest Guitarists of All Time), but his singing style has also had a huge influence on contemporaries and those who came later. Robert Plant cites him as an influence, and Moby Grape songs were part of early Led Zeppelin rehearsals, for example.

Terry Haggerty never achieved the fame Miller did, but he is accorded high acclaim from those who saw him in the Sons of Champlin or other projects. His approach to guitar wizardry doesn’t fit the usual stylistic boundaries of rock or blues. Haggerty’s Sons bandmate Bill Champlin recently posted a rave note on his website alerting everyone to the You Tube videos of the new Miller-Haggerty collaborations. “Harmonically, I hear things that are out and emotionally, that’s where I’m at,” said Haggerty. “I’ve tried to stay as true to what comes through me as I can. I’m never going to take this stuff inside me and modify it to make money. Not because I don’t need money, but because the music itself is such a wonderful, profound gift.”

Drummer Fuzzy John Oxendine has played with Miller for 40 years and was also in Sons of Champlin and the Boz Scaggs band. Bassist Keith Graves regularly works with Prairie Prince and has played in Jefferson Starship, Quicksilver Messenger Service, and It’s A Beautiful Day. Keyboardist Dale Ockerman was plunged into that rock milieu by fate, as an 18-year-old who worshiped the bands, and found himself joining Quicksilver Messenger Service in a 1971 gig at the Fillmore West, immortalized in the film “The Last Days of the Fillmore” (now out on DVD).
