Former Queens of the Stone Age bassist Nick Oliveri joined an interview with Songfacts and revealed that Judas Priest icon Rob Halford wanted to collaborate with them for one of their records.

The band dropped their second studio record entitled ‘Rated R’ on June 6, 2000, and the album’s recording session that took place in Sound City Studios became an unforgettable memory for them. Halford was also there, and it was amazing to be with the icon as a longtime Judas Priest fan.

Then, Chris Goss asked Halford to join them for the back vocals of ‘Feel Good Hit of the Summer,’ of which Oliveri had different versions. One of them was Halford saying ‘Cocaine’ with his style, which the bassist loved the most, and the other was the sinister Rob in ‘Nicotine, valium, Vicodin, marijuana, ecstasy, and alcohol’ parts.

Following the recording, the Queens of the Stone Age wanted to know how the singer should be credited on the album. Halford responded to them, saying they could write ‘Vocals by the Metal God.’ This lesser-known collaboration with Halford made the record more special for them.

Oliveri stated in his interview that:

“Indeed. We were in Studi bands came and went. We weren’t there for that long, but maybe the band Fight or Hal was there the whole time we were there. I remember being in there and Rob Halford being super cool to us.

I’m an old fan of Judas Priest; I love that stuff. It’s good rock and roll. Their early stuff is great. Chris Goss, too.

One of my favorite memories was when Chris asked Rob if he’d sing on ‘Feel Good Hit Of The Summer.’ He’s not really featured in there, but I have mixes of CDs from every day. We recorded all those sessions from ‘Songs For The Deaf’ and ‘Rated R.'”

He added:

“I took a CD home every day to see where we were because different words would come for a song, guitar parts, piano, you name it. So I have all these different versions of these songs on CDs in my house in a box.

One of them is with Rob Halford being more featured with ‘COCAINE!’ – with the Rob Halford-style singing. Josh didn’t want to put that in there. He wanted ‘the more sinister Rob’ for ‘the Nicotine, valium, Vicodin, marijuana, ecstasy, and alcohol’ parts. But I liked the ‘Cocaine’ parts with the high-pitched singing.

Stuff like that was very memorable for me – Rob Halford coming in. We asked him, ‘Hey, what do you want to be credited as?’ He goes, ‘Just put down ‘Vocals by the Metal God,’ and he walked out!”
