About David Freiberg
David Freiberg (; born August 24, 1938) is an American musician best known for contributing vocals, keyboards, electric bass, rhythm guitar, viola and percussion as a member of Quicksilver Messenger Service, Jefferson Airplane, and Jefferson Starship. Among other tracks, he co-wrote "Jane", a hit for Jefferson Starship. == Career == === Singer-songwriter === Classically trained in violin and viola, Freiberg began his career moonlighting as a coffeehouse singer-songwriter (playing acoustic guitar) during the American folk music revival while working for a railroad. For a while, he shared a house in Venice, California, with David Crosby and Paul Kantner before being briefly jailed for marijuana possession. Prior to being incarcerated, he also became acquainted with Dino Valenti, then Crosby's nominal roommate on a houseboat in Sausalito, California. During his time as a coffee house folk singer, he was part of the duo David & Michaela. They were booked to appear at the 1963 Pasadena Folk Festival on 18 August. David & Michaela made a demo at CBS studios, and "Elektra producer Paul Rothchild proposed fitting them into a bigger folk group. But the onset of the Beatles spelled the end of David & Michaela, and incentive for Freiberg to switch to rock and electric instruments." === Quicksilver Messenger Service === Following his release, Freiberg co-founded Quicksilver Messenger Service with guitarists John Cipollina, Jim Murray and Gary Duncan and drummer Greg Elmore in 1965. The founding took place shortly after Valenti, who had recently hired the musicians for his backing band following the folk rock explosion, was imprisoned for drugs.
