Speaking in a recent interview with Professor Of Rock, former Black Sabbath and Dio drummer Vinny Appice talked about the warming routines of Ronnie James Dio and Ozzy Osbourne.

Vinny stated and confirmed that Ronnie was not doing anything for warming up his voice before the live shows. On the other hand, Vinny observed that Ozzy was doing some stuff to warm up his voice.

Here’s what Vinny told about their routines:

Ronnie would be backstage. Right before the show, I’d go to his dressing room and we’d hang out. There’d be people there. He’s having a drink. And then they’d come in and go, ‘Okay, we’ve gotta go.’ And we’d walk on stage. And usually, singers warm up.

Every other singer I’ve played with tried to warm up some way or other, some with tapes. Even Ozzy Osbourne warmed up — he had the vocal tape going.”

Back in 2018, Black Sabbath guitarist and former bandmate of Ronnie James Dio, Tony Iommi, talked about his observations on Dio and said:

Ronnie had such an amazing voice — he could just do stuff that was so natural to him and he would never warm up. He had a different regime to everybody else, like Ozzy for example he always warms up before he goes on stage.

But with Ronnie, he could be sitting here talking and having a drink, and then he could go straight on stage — no warm-up — and sing like he was like a superhero.”
