To celebrate 50 years of heavy metal mastery, Judas Priest is delivering a gigantic 42-disc box set this fall.

The limited-edition set, 50 Heavy Metal Years of Music, will arrive October 15 via Sony Music. It includes remastered versions of every Judas Priest studio album and live album to date, plus 13 discs of unreleased music from the band's archives.

“Judas Priest's curated box set representing 50 heavy metal years is the ultimate treasure trove defining the band's unwavering commitment to keeping and defending the heavy metal faith,” said frontman Rob Halford in a statement.

Along with the announcement Thursday, the band unveiled a previously unreleased live track "The Hellion / Electric Eye (Live at The Summit, Houston, 1986)." Listen to it here on iHeartRadio!
