Bobby Colomby (born Robert Wayne Colomby, 20 December 1944, in New York) is an innovative jazz-rock fusion drummer, and an original member of the group Blood, Sweat & Tears. He's also the uncredited drummer on John Cale and Terry Riley's collaboration album Church of Anthrax.
He graduated from the City College of NY with a degree in Psychology, and his elder brother Harry Colomby was the manager of Thelonious Monk.
Colomby played on the self-titled Blood, Sweat & Tears' 1970 Grammy Award for Album of the Year, which features the hit songs: "Spinning Wheel", "And When I Die", and "You've Made Me So Very Happy" (all sung by David Clayton-Thomas). After many changes in the group he became (in the end) the defacto owner of Blood Sweat & Tears name.
Colomby produced jazz bass virtuoso Jaco Pastorius' first solo album; The Jacksons' comeback album Destiny; Chris Botti's albums December, When I Fall In Love, To Love Again and Italia; Paula Cole's album Courage and Jeff Lorber's album He Had a Hat.
For a few years in the late 1980s Bobby Colomby was a reporter for the television programs Entertainment Tonight and "The CBS Morning Program." He also hosted "In Person from the Palace".
In 2000, Colomby and Richard Marx created Signal 21 Records. The label released only one album, Richard Marx's Days In Avalon before the label folded shortly thereafter.
Colomby is married to Donna Abbott, a graphic designer and native of California.
