Killing Machine is the fifth studio album by British heavy metal band Judas Priest, released in November 1978. The album saw Judas Priest head towards a more commercial Van Halen Scorpions did with their album Lovedrive however it did still contain the dark lyrical themes as heard in their previous albums. At about the same time, the band members adopted their now-famous image. Killing Machine was retitled Hell Bent for Leather for US release, as the US branch of Columbia/CBS did not like the “murderous implications” of the album title.”The Green Manalishi (With the Two-Pronged Crown)” an early Fleetwood Mac cover, was added to the running order in the US.
The album was remastered in 2001, with two bonus tracks added (three in the UK). The bonus track “Fight for Your Life” was the “original” version of Judas Priest’s “Rock Hard Ride Free” from their Defenders of the Faith album. “The Green Manalishi (With the Two-Pronged Crown)” is considered a bonus track on the UK remaster, but a regular track on the US version.In 2010, label Audio Fidelity released a limited-edition 24-karat gold CD of the album. Mastering was done by Steve Hoffman. This does not contain the bonus tracks from the 2001 edition.
