Survivor is an American rock band formed in 1977 by core members Jim Peterik and Frankie Sullivan. The band achieved its greatest success in the 1980s with its album-oriented rock (AOR), which garnered many charting singles, especially in the United States. They had hits like "Eye of the Tiger", "Burning Heart" (US #2), "The Search Is Over" (#4 US), and "High on You" (#8 US). The band tweaked its musical direction in 1988 with the release of the slightly heavier Too Hot to Sleep
