This is the Backing Track without Vocals and Guitar from Maniac.
“Maniac” is a song performed by Michael Sembello. The song was used in the 1983 film Flashdance.
“Maniac” appears during an early scene in Flashdance and is used as the backing track of a montage sequence showing Alex (Jennifer Beals) training strenuously in her converted warehouse.
The song was included in Flashdance after Sembello’s wife accidentally included it on a tape sent to executives at Paramount Pictures who were looking for music to use in the film.
A dance music version was released in 2000, by Irish DJ Mark McCabe, entitled “Maniac 2000”.
