Ozzy Osbourne has launched a Facebook page for a forthcoming attraction called "Ozzy Osbourne's Hell Gate". The BLACK SABBATH frontman has yet to reveal any details regarding the event, which is said to be "coming October 2015." Some fans have speculated that Ozzy has rejoined forces with Universal Studios Hollywood for the annual "Halloween Horror Nights" event. Ozzy and the rest of BLACK SABBATH were featured in last year's all-original 3D maze "Black Sabbath: 13 3D" at Universal Studios Hollywood. The maze was based on the darkest lyrics from BLACK SABBATH's biggest hit songs and was the only attraction at the horror event to incorporate 3D video. It also included scenes inspired by the legendary band's comeback album, "13". Ozzy will release a solo career retrospective titled "Memoirs Of A Madman" on October 7. His last solo studio effort was 2010's "Scream". Ozzy's first album under the SABBATH banner in 35 years, "13", came out in June 2013 and topped both the U.S. and U.K. album charts, later winning a Grammy Award as well.
