Unusual Heat is the seventh studio album by British-American rock band Foreigner, released on June 14, 1991, by Atlantic Records. Recorded at several different studios across the state of New York and England, and produced by Terry Thomas and Mick Jones, it was the only album with lead singer Johnny Edwards. He replaced original lead singer Lou Gramm after the latter had parted company in 1990. Edwards, a veteran singer who'd done a tour of duty with Montrose and was then the frontman for another Atlantic act, Wild Horses. As Edwards told UCR in a separate interview, Wild Horses had only just signed its record deal — and although joining for Foreigner was obviously tempting for financial reasons if nothing else, he was reluctant to walk away from his own band after struggling for years to make it on his own terms.

Foreigner is a British-American rock band formed in New York City in 1976 by guitarist Mick Jones, vocalist Lou Gramm, drummer Dennis Elliott, keyboardist Al Greenwood, bassist Ed Gagliardi and multi-instrumentalist Ian McDonald, the last of whom was also a founding member of King Crimson.
