The singer, who is currently promoting his Celestial Christmas album, spoke about the idea – based on thrash metal's Big Four of Metallica, Slayer, Megadeth and Anthrax – during an interview with Consequence Of Sound.
“My dream had always been to have like ‘The Big Four of the UK’, without turning this into a kind of depressing way,” said Halford. “I’d always dreamed of Black Sabbath and Motorhead and Priest and Maiden as ‘The Big Four’ doing something in the UK.”
He continued, referring to the death of Lemmy and Black Sabbath's retirement, saying, "Sadly, two-fourths of that has gone, but the music lives forever. That’s the main thing.”
Last week, Judas Priest's Glenn Tipton thanked Priest fans after what's been a tough year for the guitarist. He issued a statement addressing his ongoing battle with Parkinson’s disease in March 2018, with his Priest bandmates then setting up the Glenn Tipton Parkinson’s Foundation in the summer of last year which has now raised more than $150,000.
Also last week, it was confirmed that Judas Priest would headline the UK's Bloodstock Open Air in 2020 to celebrate their 50th anniversary.
At the weekend, former Judas Priest guitarist K.K. Downing played a one-off set of Priest classics alongside Megadeth's David Ellefson in Wolverhampton.
