System Of A Down, Static-X, Sugar Ray, Everlast, Sevendust, and Black Sabbath cornerstones Ozzy Osbourne and Tony Iommi are among the hard rock heavyweights saluting hip-hop on an upcoming tribute album.

Static-X will be hooking up with Dead Prez in a Los Angeles studio next week to record a cover of the Dead Prez track "Hip-Hop" for the genre-bending salute to rap label Loud Records.

Other cuts for the album will find Ozzy and Iommi teaming with the Wu-Tang Clan on "For Heavens Sake," Sevendust joining Xzibit for "What You See Is What You Get," Everlast cutting a track with Mobb Deep, Sugar Ray recording with Tha Alkaholiks, and System Of A Down meeting Wu-Tang maestro Rza to cover "Shame on a Ni**a.

The ambitious project is tentatively due to hit stores this fall.
