Unleashed in the East is Judas Priest's first live album, recorded live in Tokyo, Japan during the Hell Bent for Leather Tour in 1979. It was released in September 1979 and became the band's best-selling album up to that point, reaching the US Top 100 and the UK Top Ten., eventually the album became one of the five Judas Priest albums to gain a RIAA platinum certification. To which extent the album was really live remains a matter of contention, with the album sometimes being called Unleashed in the Studio. Years later, after he had left Priest, Rob Halford noted in various interviews that the music was indeed live, but that his vocals had been ruined in the original recording and were later dubbed in a concert-like studio setting.
