Rubicon was formed in San Francisco by Jerry Martini, who was an original member of Sly & the Family Stone. Other members of the group included Greg Eckler (vocals, drums), Brad Gillis (guitar), Max Haskett (lead vocals, horns), Dennis Marcellino (sax, vocals), Jim Pugh (keyboards) and Jack Blades (bass). Their first album, the self-titled Rubicon, released in 1978, generated their only chart single. They released a second album in 1979, entitled America Dreams, before disbanding. Brad Gillis and Jack Blades went on to form Night Ranger, which would go on to great success in its own right.
Rubicon reformed in the early 90's as a progressive rock band with Greg Eckler (drums), Chuck Crenshaw (keyboards), J.P. Michaels (vocals, bass guitar), David Christians (vocals, lead guitar), and Randy Newhouse (acoustic guitar). This version of Rubicon produced one CD called Best of Rubicon and produced a single, "Whipping Boy," written by Michaels and Crenshaw, that was played on many radio stations nationally and gained recognition among independent critics.
