Judas Priest are an English metal band from Birmingham, formed in 1968. Judas Priest's core line-up consists of vocalist Rob Halford, guitarists Glenn Tipton and K.K. Downing, and bassist Ian Hill. The band has gone through several drummers over the years, though Scott Travis has held the position since 1989 and is the band's longest-serving drummer. In 1978 Rob Halford began incorporating a macho image of what today is known as hardcore metal/biker/S&M style, into his look and the rest of the band followed. It became a mainstay in heavy metal even today, and sparked a revival in metal in the early '80s, catapulting them to fame in both the mainstream and underground. MTV has hailed them as the second greatest influence to heavy metal behind Black Sabbath for both their imagery and musical artistry.
For the release of their debut album Rock and Rolla in 1974 the band hired Rodger Bain after recommendation from their record company. Bain and the record company suggested they add another member to the band and also made quite a few changes to the album that the band did not agree with. The album was released to mediocre reviews, and sales were were not met by the hype surrounding them. For their next release in 1976 however, The Sad Wings of Destiny, the band hired a new producer and decided to include some old material that had been cut from the previous album by then producer Bain. The album was a success and just several years later they had released a Live album Unleashed in the Middle East which was the first of a string of albums to go platinum. Judas priest are acclaimed as one of the pioneers of metal where they brought a harder more metallic sound to the rock music of the day. To date, they have released 16 albums and sold over 30 million record world wide earmarking them as metal greats.
