What are Ozzy Osbourne and Corey Taylor up to? That remains to be seen, but the two rockers are teaming up for a special event in Hollywood this Thursday (May 12).

The event is set to take place at noon PT at the Hollywood Palladium in Los Angeles, and a limited number of fans will be allowed to attend. There will a small amount of spots based on capacity and there will be no lineups allowed at the venue prior to 7AM.

There has been no indication as to what the announcement may be. However, both Osbourne and Taylor have had ties to their own festivals over the years -- Osbourne with Ozzfest and Taylor as part of Slipknot with Knotfest. Osbourne is spending the year touring with Black Sabbath as part of the band's final tour, while Slipknot have already announced a summer tour with Marilyn Manson.

Stay tuned to see what the two musicians have to reveal at the Thursday event.
