Feinstein is the cousin of Ronnie James Dio and used to be a member of the '70s band Elf with his famous cousin. When plans to write and record again with Dio were cancelled, Feinstein still recorded the tracks locally in New York and released them as a 'solo' album. The debut album also features backing vocals by The Rods' Garry Bordorano. Late 2001 sees the recording of a second album.
David and royal Hunt singer John West formed Feinstein in 2004. An Album called Third Wish was soon devised.
