Survivor's brand of melodic, hard AOR netted the group several hits through the '80s, including two smash themes from Rocky films, but never quite matched the success or consistency of contemporaries like Foreigner. Survivor was founded in 1978 by guitarist/keyboardist Jim Peterik, formerly the lead singer of the Ides of March, and guitarist Frankie Sullivan; the two recruited lead singer Dave Bickler and recorded a self-titled debut album as a trio with studio musicians Dennis Johnson on bass and Gary Smith on drums. Their places were taken by permanent members Stephen Ellis and Marc Doubray, respectively. The group's big break came in 1982 when Sylvester Stallone commissioned them to write the theme to Rocky III; the result, "Eye of the Tiger," was an instant hit with its bombastic opening riff and anthemic chorus. It spent six weeks at number one on the Billboard charts and pushed the accompanying album of the same name over the one million sales mark. Bickler quit in 1983 due to medical reasons and was replaced by former Cobra singer Jimi Jamison. The shakeup gave the band a kickstart, and they had two Top Ten hits in 1985 with "High On You" and "The Search Is Over." The band's theme from Rocky IV, "Burning Heart," provided their second biggest hit in 1986, but their fortunes slid downhill from there; by the end of the year, Jamison, Peterik, and Sullivan were the only remaining members, and Survivor finally disbanded in 1989. Bickler, Sullivan, Ellis and Doubray returned to the studio as Survivor in 1997; Jamison later returned to the lineup as well. ~ Steve Huey, All Music Guide
