Mainstream Success

Following the release of Killing Machine was the live release from the supporting tour, entitled Unleashed in the East. It was the first of many Judas Priest albums to go Platinum. At the time, there was some criticism of the band's use of studio-enhancements and overdubbing in what was marketed as a live album.

After Les Binks quit, in part because of the band's direction, the band replaced him with Dave Holland, formerly from the band Trapeze. With this line-up, Judas Priest recorded six studio and one live album which garnered different degrees of critical and financial success. Overall, the band has sold in excess of 30 million albums globally.

In 1980, the band released British Steel. The songs were shorter and had more mainstream radio hooks, but retained the heavy metal feel. Tracks such as "United", "Breaking the Law", and "Living After Midnight" were frequently played on the radio. The next release, 1981's Point of Entry, followed the same formula, but critics generally panned it. However, the tour in support was successful, with new songs such as "Solar Angels" and "Heading Out to the Highway".

The 1982 album Screaming for Vengeance featured the song "You've Got Another Thing Comin'", which garnered strong US radio airplay. Songs such as "Electric Eye" and "Riding on the Wind" also appeared off this album, and proved to be popular live tracks. "(Take These) Chains" (by Bob Halligan, Jr.) was released as a single and received heavy airplay. This album went two times Platinum.

Defenders of the Faith was released in 1984. Even though it was more progressive than their earlier efforts, some critics dubbed it as "Screaming for Vengeance II", due to its musical likeness to the previous album.

On July 13, 1985, Judas Priest was - apart from Black Sabbath - the only metal band to perform at the Live Aid event. The band played at JFK Stadium in Philadelphia. Their setlist was "Living After Midnight", "The Green Manalishi (With The Two-Pronged Crown)" and "(You've Got) Another Thing Comin'".

Turbo was released in April 1986. The band adopted a more colourful stage look and gave their music a more mainstream feel by adding guitar synthesizers. The album also went Platinum and had a successful tour in support. A live album recorded on the tour, titled Priest...Live!, was released the next year, offering fans live tracks from the 1980s era. The video documentary Heavy Metal Parking Lot was created by Jeff Krulik and John Heyn in 1986. It documents the heavy metal fans waiting on May 31, 1986 for a Judas Priest concert (with special guests Dokken) at the Capital Centre (later renamed US Airways Arena) in Landover, Maryland.

In May 1988, Ram It Down was released, featuring several reworked songs left over from Turbo, in addition to new songs. A reviewer has called Ram It Down a "stylistic evolution" that resulted from the band's "...attempt to rid themselves of the tech synthesiser approach...and return to the traditional metal of their fading glory days." The reviewer argued the album showed "...how far behind they were lagging...the thrashers they helped influence" in earlier years. As well, in the late 1980s, longtime drummer Dave Holland left the band.

In September 1990, the Painkiller album used a new drummer, Scott Travis (formerly from Racer X). This comeback album dropped the 1980s-style synthesisers for all of the songs except "A Touch of Evil." The tour used bands such as Pantera, Megadeth and Sepultura as opening bands, and culminated in the Rock in Rio performance in Brazil in front of 100,000+ music fans.

Part of the Judas Priest stage show often featured Rob Halford riding onstage on a Harley-Davidson motorbike, dressed in motorcycle leathers and sunglasses. In a Toronto show in August 1991, Halford was seriously injured as he rode on stage, when he collided with a drum riser that was hidden behind clouds of dry ice mist. Although the show was delayed, he performed the entire set before going to hospital. Hill later noted "he must have been in agony". In a 2007 interview Rob later claimed the accident had nothing to do with his departure from the band. For nearly five years, Judas Priest remained dormant, with no release to top Painkiller.
