Megadeth have shared a preview of the new song "Don't Turn Your Back" from their forthcoming release Supercollider. The album is out June 4. The new song finds Dave Mustaine and co. playing with a renewed sense of ferocity. It's only about 30 seconds long, but it's enough to send adrenaline coursing through your veins. Check it out here.

Black Sabbath will appear on the season finale of CSI. The episode airs on May 15 at 10PM on CBS. The band will perform the new song "End of the Beginning" from their forthcoming album, 13, out June 11. Ted Danson's character D.B. Russell will attend a Black Sabbath gig and that's how the song will factor into the show. Cool, right?

Dave Lombardo may have gotten the boot from Slayer over contractual issues, but he's not sitting idly by. We all know idle hands are the devil's workshop and Lombardo is putting his famous hands and feet to good use again by resurrecting his Grip Inc. project. Amen's Casey Chaos will replace the late Gus Chambers on vocals. This ought to be interesting, to say the least. [The PRP]

GWAR's annual GWAR-B-Q, now in its fourth glorious year, will take place at Hadad's Water Park in Richmond, Virginia. The fun will be unleashed on Saturday, Aug. 17. Doors open at 10AM, with the first band to commandeer the stage at 11AM. Municipal Waste, Corrosion of Conformity, Pig Destroyer, Cannabis Corpse, Loincloth, and our personal faves, Kung-Fu Dykes, are set to perform, among others to be announced at a later date.

"Once again we blow the horn of war and set into motion the gears that grind us towards the greatest Gwar-B-Q yet," said Oderus Urungus, the cod piece behind GWAR. "We will not only be rockin' like Dokken and slippin' the cock in, but we will shoving a wealth of GWAR products down your throat...not only our new Gwar-B-Q sauce, but our very own beer, Impaled Ale! Eat and drink yourself into a diabetic stupor, then puke it all up in the slam pit! It's gonna fucking rule!"

Who would dare to miss such an event?
