1. Prophet was founded in 1980s by two previously members of Icarian and Tom Fuller's Rock City, bassist Scott Metaxas and keyboardist Joe Zujkowski. For completing the group, they invited other four members: Ken Dubman (guitar), William Runco (guitar), Bob Butterfield (drums) and Marc Hoffman (vocals). The band started its career playing in covers of songs by bands such as Queen, Boston, and Styx. In fact, they was considered one of the best cover bands in New Jersey in the 80s.
In 1985, Hoffman and Butterfield left the band and were substituted by the late Dean Fasano (vocals) and Ted Poley (drums). Poley played with Dubman years before in another rock band, named Lush, when they were in High School. William Runco also left the band, but was not replaced by another musician. With this new formation, the group recorded its first album, self-titled. It includes the song "Slow Down", which may have influenced the hit "Wanted Dead or Alive", by Bon Jovi, years later.
After releasing the first album, Fasano and Poley left the band. Poley joined the band Danger Danger as its vocalist and bandleader. Then, Prophet invited Russell Arcara (vocals) and Michael Sterlacci (drums). During this period, the band was managed by Noel Monk, who also managed Van Halen. This lineup recorded the band's second album of the band, Cycle of the Moon. This album is considered the most important by the group  and peaked at 137 on the Billboard 200.
In 1991, Prophet released its third album, Recycled, with yet another lineup: Dave DiPietro (guitar) joined the band and Sterlacci was replaced by Jim Callahan. This album also had Karl Cochran (acoustic guitar and backing vocals) as a special guest.
From 1992, Prophet's member started new projects and the group ended years later. Arcara created two other bands after leaving Prophet: Arcara and The Way. In 1992, Metaxas and DiPietro joined Nuclear Assault. Dubman joined the blues band Rocket 88. Callahan created a software company and started working as a graphic designer.
Years later, Dubman, Arcara, Metaxas and Callahan created a tribute band, Edgar Cayce, after the American prophet. The band's albums were re-released many times in 2000s: Recycled was reissued in 2005 (Z Records) and Cycle of Moon was reissued in 2005 (Z Records) and 2009 (Wounded Bird Records).
