Steel Dragon is the name of a fictitious heavy metal band featuring real musicians, created to appear in the Warner Bros. movie Rock Star (2001), inclusively being responsible for the movie's original soundtrack. The members, especially the lead singers, had an over the top look and attitude similar to those seen in some famous heavy metal bands of the '80s.
The band's formation on-screen included the talents of four musicians and had actors playing the role of the lead singers, who actually were dubbed by vocalists Jeff Scott Soto (Talisman, Yngwie Malmsteen's Rising Force, Journey) and Michael Matijevic during their performances, except for Myles Kennedy, who did the actual singing himself during his brief scene during the movie.
Also, there were other additional musicians who gave their contribution to help in the process of composing and performing the songs, as listed below:
Zakk Wylde (Black Label Society, Ozzy Osbourne) - Guitarist "Ghode"
Jeff Pilson (Foreigner, Dokken) - Bassist "J?rgen"
Jason Bonham (Foreigner, Led Zeppelin) - Drummer "A.C."
Jason Flemyng (Actor) - Lead singer "Bobby Beers"
Jeff Scott Soto (Talisman, Yngwie Malmsteen's Rising Force, Journey, Axel Rudi Pell) - Lead vocals for "Bobby Beers"
