AceShowbiz - Metallica were saluted by Deep Purple's Ian Paice and Roger Glover as they picked up the 2018 Polar Prize in Sweden on Thursday, June 14.
Lars Ulrich and Robert Trujillo accepted the music award in Stockholm from His Majesty King Carl XVI Gustaf after the British rockers paid tribute to the group.
Glover recalled hearing Metallica for the first time at a festival in the early 1980s, stating, "I'd heard the name, didn't know anything about them. I went on the side of the stage to have a look and thought, 'Yes, there's something happening here'.
"The audience was singing every word they sang. And that's what impressed me, when you touch that many people with your music there is something special going on".
Accepting the award, Danish drummer Ulrich said, "Who would have thought, when Metallica started this musical journey 37 years ago, that one day we would be standing in front of both musical royalty and actual royalty, accepting one of the most prestigious prizes that can be bestowed upon musicians?.
"From the beginning, we always felt like outsiders. We always felt, like, somehow we were not good enough, not cool enough to be accepted by a general music audience... then an unexpected thing happened. The mainstream audience began moving closer and closer to the area where the musically disenfranchised like ourselves were hovering".
He added, "Receiving this prize solidifies the idea that no matter how alienated you feel, connecting to other people through music is not only possible but can be outright inspirational and life changing".
The Polar Prize, established by ABBA manager Stig Anderson 28 years ago, comes with a cash gift, which Metallica plan to pass to charity.
