Metallica cover Judas Priest's 'Delivering The Goods' with Lars Ulrich on vocals

Uploaded by fan account Metallica Live HD, the clip was filmed in the Tuning Room – a space where Metallica warm up shortly before taking to the stage at their live shows - at PPG Paints Arena in Pittsburgh on 18th October 2018.

Clearing not taking themselves too seriously, at around the seven-and-a-half minute mark in the video the band launch into ‘Delivering The Goods’ with Lars doing his best guttural growl. Watch it right here:

Commenting on how Judas Priest influenced Metallica, James Hetfield told Billboard in 2014: "Judas Priest is everything (Metallica) wanted to be as a band starting out. If someone asked you to define what heavy metal is, that's one of the bands you'd show them."

Lars Ulrich told Rolling Stone in 2017: “Other bands like Motörhead and Deep Purple had one guitar player and they were doing different things, more of a layering thing, but when it came to Judas Priest, they had the guitarists coming together and playing the same riff.

“It just doubled up and gave it a heavier, bigger sound and made it thicker and more immersive.”

Judas Priest’s Rob Halford is also a keen Metallica fan and lists ‘Kill ‘Em All’ as his second favourite metal album of all time behind Black Sabbath’s eponymous debut. He has also guested on stage with Metallica several times over the decades to perform ‘Rapid Fire’.  

Don’t forget, Metallica play two massive stadium shows at Manchester Etihad Stadium on Tuesday 18th and London Twickenham Stadium on Thursday 20th June with special guests Ghost. Tickets are on sale from sale from Planet Rock Tickets now.
