Judas Priest frontman Bob Halford recently had an interview with Austraila’s May The Rock Be With You, and reveals the biggest ‘life changin’ moment in his life.

Halford said that quitting drinking and his drugs 33 years ago was the life changer. He also stated that he had to do that because vocals is a physical performance.

Here is what he says about how he keeps his voice in healty shape:

“If I knew, I would be, like, ‘It’s a dollar! Take a sip each night.’ I don’t know what it is; I really don’t know what it is. I think one of the big life-changing moments is when I quit my drinking and my drugs 33 years ago because vocals is a physical performance.

You have to get your rest and have all the right components in place to be able to give the performance you can give either in the studio, but primarily, on the road. And the roadwork is grueling, as far as the travel. You notice when you go on a holiday, you take one flight and you’re away from a week and you come home and you go ‘I can’t do that again.

I need a year to recover.’ Imagine doing that pretty much every other day for your life in 50-odd years. You do have to acclimatize and make the right adjustments for your physical performance in the voice. It’s technique more than anything else.”

What’s the next step for the Judas Priest?

“I would say much of the same. The fact is, Priest is on a roll and we’re on fire with this music and the reaction, the support from our fans and everybody is what gives you that thought of, ‘What would happen if we wrote another song? Then another song? Then an album? We might as well go out and tour again.’

It’s a lot of things combined that really still keep us active and keep us to what’s next to be done. Each PRIEST album, if you think about it, is by definition, has its own character and sound.”
