Ozzy Osbourne and Black Sabbath have joined together for the first time on a studio album since 1978. The upcoming studio record is set for release on June 11. Black Sabbath have unleashed the first tune from "13" called "God Is Dead ?."

From my first listen it reeks of classic Black Sabbath; signature Tony Iommi power chords, Ozzy sounding better than ever with Gezzer Butler and Brad Wilk (Rage Against the Machine) laying down some serious thump.

The band will tease us with another track called "End of the Beginning" on the season finale of CSI on CBS May 11.
