Killing Machine is the fifth studio album by English heavy metal band Judas Priest, released on 9 October 1978 by Columbia Records. The album pushed the band towards a more commercial style while still featuring the dark lyrical themes of their previous albums. At about the same time, the band members adopted their now-famous "leather-and-studs" fashion image, inspired by Rob Halford's interest in leather culture. It is the band's last studio album to feature drummer Les Binks. In the United States, it was released with a different track listing as Hell Bent for Leather due to controversy over the Cleveland Elementary School shooting.
