'' Killing Machine '' ( known as '' Hell Bent for Leather '' in the US due to controversy over the Cleveland Elementary School shooting ) is the fifth studio album by British heavy metal band Judas Priest . With its release in October 1978 , the album pushed the band towards a more commercial style ; however , it still contained 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 gay leather culture . It is the band 's last studio album to feature drummer Les Binks
