As expected, a new hard rock festival called Power Trip, from the founders of Coachella, has announced its lineup: Metallica, Guns N’ Roses, Ozzy Osbourne, AC/DC, Iron Maiden and Tool. It will take place at Coachella’s home base of the Empire Polo Grounds in Indio, Calif., Oct. 6-8, according to report by Variety.

Out of the handful of features that Post Malone has included on his Friday release Hollywood's Bleeding, Ozzy Osbourne is probably the most unexpected. The legendary musician partnered with Post and Travis Scott to deliver their rock-heavy collaboration, "Take What You Want."

Superstar rapper Post Malone has revealed a number of guest appearances on his upcoming album Hollywood's Bleeding, and among them is none other than the Prince of Darkness himself, Ozzy Osbourne.

Earlier this year, Black Sabbath were among the acts chosen for recognition by the Recording Academy for a Grammys Lifetime Achievement Award. Tony Iommi, Geezer Butler and estranged drummer Bill Ward all showed for the ceremony, but Ozzy Osbourne was conspicuously absent.

Black Sabbath played their final show on Feb. 4 of 2017 and, like the rest of the farewell shows, they did it without original drummer Bill Ward. Ozzy Osbourne has been outspoken about his former bandmate's current physical state, but recently bemoaned the fact that the drummer wasn't part of Sabbath's final chapter.
