After 40 years of air-horn vocalizing, Rob Halford admits to a little wear and tear, even as Judas Priest's on-going U.S. tour in support of 'Redeemer of Souls' continues.

“I get frustrated," Halford tells One On One With Mitch Lafon. "I freely admit that I wish I could do the stuff I could do when I was laying down tracks in 1974 or 1975, but that’s just ridiculous. I don’t think any singer can requalify those moments again. You go out and do your best."

That said, Halford says he gave it his all on the return-to-form rocker 'Redeemer,' Judas Priest's first studio effort since 2008's long-form narrative effort 'Nostradamus.'

“I’d like to feel that what I’m trying to do on 'Redeemer Of Souls' are the best examples of my abilities right now," Halford adds. "I’m going to places that I can go to. I’m not pulling back in any areas."

Judas Priest heads to Brooklyn, N.Y. next for an October 9 show, followed by dates in Atlantic City and Mashantucket, Connecticut on October 10-11, respectively. They're on the road in America through November 22 with stops in Pittsburgh, Detroit, Baltimore, Los Angeles, Phoenix and Las Vegas.
