Survivor, an American rock band, formed in Chicago in 1978 around Jim Peterik and Frankie Sullivan. The band achieved its greatest success in the 1980s, producing many charting singles, especially in the United States. The band arguably became best-known for its double-platinum-certified 1982 hit "Eye of the Tiger", the theme song for the 1982 motion picture Rocky III (US number 1 for 6 weeks); singles like "Burning Heart" (US number 2), "The Search Is Over" (US number 4), "High on You" (US number 8), "Is This Love" (US number 9) and "I Can't Hold Back" (US number 13) continued to chart in the mid-1980s.
The band tweaked its musical direction in 1988 with the release of the slightly heavier Too Hot to Sleep, but due to lackluster promotion the album barely reached the Billboard 200 in the United States.
Singer Jimi Jamison later toured as "Survivor" in the mid-1990s without the permission of the rest of the band, but reunited with guitarist Frankie Sullivan in 2000. The band then released Reach in 2006, but Jamison left again after its release and was replaced by singer Robin McAuley. Survivor continued to tour with McAuley into 2011 until Jamison returned later that year.
In April 2013 the band's official media sources announced that guitarist Frankie Sullivan had reunited the current Survivor line-up with original singer Dave Bickler and the band would have Bickler and Jamison together for the next tour.On September 1, 2014 Jamison died in his home in Memphis, Tennessee, at the age of 63. His autopsy; released on November 11, 2014; revealed the cause of death as a hemorrhagic brain stroke, with "acute methamphetamine intoxication contributing".
