Looks like Ozzy is replacing guitarist Zakk Wylde. This from FMQB:

Ozzy Osbourne has been working on his tenth studio album for quite some time, but now it looks like he is looking for a new guitarist to fill the shoes of Zakk Wylde. Apparently the Ozzman just wants to get some new, unique sounds on his CD, since he feels like Wylde’s work was sounding too much like his other band, Black Label Society. Ozzy has been auditioning several candidates, and one possibility is guitarist John 5 (ex-Marilyn Manson, currently with Rob Zombie).

“I’m getting a new guitar player as we speak,” Ozzy told Classic Rock magazine. “And everyone has been saying to me for a long time, ‘Get Johnny 5!’ I tried him at one time and I didn’t really give him a chance. We’ll see, I don’t know. I haven’t fallen out with Zakk, but Zakk’s got his own band, and I felt like my stuff was beginning to sound like Black Label Society. I just felt like I wanted a change.”

This is like a rare solar eclipse or comet sighting. Ozzy has had many band members over the years, but he’s only had a few long-term guitar replacements. Zakk Wylde replaced Jake E. Lee in 1987, and Jake E. Lee replaced the late-great Randy Rhoads in 1982. That’s basically it. Other guitarists have played with Ozzy over the years (Steve Vai, Alex Skolnick, Brad Gillis, Joe Holmes, Jerry Cantrell, and Bernie Tormé), but none have contributed to Ozzy’s studio albums like the big 3.
