The horror-flick fan's dream come true, "Freddy Vs. Jason" not only looks scary, it sounds equally frightening.

New and previously unreleased tunes from Slipknot and Ill Nino, and a collaboration between Mike Patton and Sepultura lead the charge on the film's soundtrack, which is slated for release August 5, according to a Roadrunner Records spokesperson.

Slipknot's "Snap" was recorded during the sessions that yielded 1999's eponymous breakthrough LP but never saw the light of day until now, while Ill Nino's "How Can I Live" will serve as the soundtrack's single, and also appear on the band's second album, Confession, due September 30. A video for the song will be shot July 8 in Los Angeles.

Former Faith No More and current Fantômas singer Mike Patton recorded "The Waste" with Brazilian metalheads Sepultura during their sessions for 1998's Against, the band's first album without founding singer Max Cavalera.

Rare tracks on the LP include Chimaira's "Army of Me" and Stone Sour's "Inside the Cynic," both of which had only been available as imports. Former Coal Chamber frontman Dez Fafara's new band, Devildriver, makes its debut with "Swinging the Dead," which is also expected to appear on the group's first LP, expected this fall.

The "Freddy Vs. Jason" soundtrack will also be available in three versions: one for "Friday the 13th" fans, with Jason only on the cover; one for "A Nightmare on Elm Street" fans, featuring Freddy's burnt-up mug; and a third with both on the cover.

"Freddy Vs. Jason," which features Destiny's Child's Kelly Rowland as one of the female leads, hits theaters August 15 (see [article id="1457125"]"Kelly Rowland Takes On Freddy Krueger, Jason Voorhees"[/article]).
