Testament guitarist Alex Skolnick recounted his brief stint with Ozzy Osbourne's band, recalling his first rehearsal with Ozzy. Check it out:
“When I played with Ozzy for the first time… Everyone had told me that Ozzy hates rehearsing: ‘Look, this is what’s going to happen; he’s going to come into the room and announce a song. It doesn’t matter what the song is, just know how to play it. It’ll be one of these,’ so they gave me a list. ‘Don’t tune your guitar, you don’t need to. If your amp is making noise, turn it off. He hates noise.’ So there’s a whole preparation process. Of course, when he came into the room he came in and announced a song. Apparently it was good because then I knew we were going to do this surprise show. But then came ‘we’re not going to do it anymore because he has a sore throat.’ And then it’s ‘No, now we’re going to do the show.’ And this show was announced and canceled so many times… And in the end it was approved.”.
I remember one time... He was using a teleprompter. And that's no secret anymore, right? And believe me, he's not the only musician who uses one. But they were doing teleprompter operator tests. And it was a nice girl's turn. She had never worked with him before. And at one point she made a mistake, and I knew she wasn't going to get the job. Because she had pressed the wrong button and the music disappeared. And he was watching. And then he looked back, and I swear, it was the most evil look I've ever seen in my life. It was like Satan. But at the end of the show, he gave me a hug and told me I was hired, and everyone congratulated me. I thought it was amazing.”.
Skolnick was eventually fired from the band by Sharon Osbourne, who decided to hire guitarist Joe Holmes: “Everything worked out for the best in the end, because working with Ozzy made me delve deeper into Jazz and my whole career would have been different if I had stayed with Ozzy. But I am very grateful for the experience.”
