Crazy Nights is the fourteenth studio album by American rock band Kiss, recorded from March to June 1987 and released on September 21, 1987, by Mercury worldwide and Vertigo in the UK. This was the second album to feature the line-up of Gene Simmons, Paul Stanley, Bruce Kulick, and Eric Carr. The album is notable for its pop-metal sound as well as for its use of keyboards and synthesizers, a reflection of popular trends in the commercial rock genre of this time. It was re-released in 1998 as part of the Kiss Remasters series and is the last Kiss album to have been remastered.
