The San Francisco-based Rova Saxophone Quartet was the alternative, experimental alter-ego of the more famous World Saxophone Quartet. Formed in 1977 by Jon Raskin (1954), Larry Ochs (1949), Andrew Voigt and Bruce Ackley, on respectively baritone, tenor, alto and soprano saxophone it straddled the border between free jazz and classical music of the 20th century. Raskin had already founded several multimedia projects and worked with composer John Adams.
