The following description comes from the event organizer.

Zero was founded by Steve Kimock and Greg Anton in the early 1980’s in Marin County, California. Over the years they’ve been joined by a host of musicians from the psychedelic caravan who share a common spirit. Their music is a unique mixture of free-flowing jazz, blues, and rock improvisation....the lyrics to their original vocal songs are written by Robert Hunter.

A Zero show is a musical journey that spans the spectrum from delicate ballads to blow-the-roof-off rock & roll. After nine albums and over 1300 shows, the band has become a San Francisco musical institution.

Zero has recently regrouped, reenergized and is hitting the road with Steve Kimock; guitar, Greg Anton; drums, Pete Sears; bass, Hadi Al-Saadoon; trumpet, Spencer Burrows; keys & vocals with some special guests in the wings.
