Deluxe double 180gm blue vinyl pressing in gatefold sleeve. In 1986, Judas Priest intended to record a double album called Twin Turbos of which half would be lighter, more commercial Rock, and the other half would be similarly polished but heavier and less synth-driven. As it happened, record labels being notoriously timid about double albums, the project was split into two releases, with the heavier Twin Turbos material being relegated to Ram It Down. Back On Black. 2010.
