Ozzy, getting rid of Zakk is one of your biggest mistakes. I know you think you are beginning to sound like Black Label Society but have you ever considered that Black Label sounds like Ozzy and that it´s not Ozzy who sounds like Black Label?
I saw your new guitar player on youtube (blizzcon) and he is just a poor guitarplayer compared to Zakk. Not the same thing at all.
For f*** sake, get Zakk back in and start making some serious music!!
