The band's next album, 1980's Glory Road, was a top ten hit in the UK. The band's sound was drifting closer and closer to heavy metal. Album opener "Unchain Your Brain" is a great proto-metal tune.
The band's 1981 album Future Shock would hit number two on the UK album charts. The title track is a great hard rocker.
As the cover art would indicate this is a heavy metal album, tried and true. Check out "The Ballad of the Lucitania Express."
In that same year, 1981, Gillan would release a double album called Double Trouble, the first record containing brand new studio recordings and the second record live recordings. The band mellowed out on the studio stuff and the keyboards gained more prominence. It was at this point that Bernie Torme quit the band, apparently over a money dispute. He would soon resurface as a temporary, emergency replacement for Randy Rhoads on the Diary of a Madman tour. Torme's replacement in Gillan would be future Iron Maiden member Janick Gers.
Janick Gers' time in the band would be short-lived. The band's next album, Magic, was not their best work, but had its moments.
Magic would be the band's swan song. Ian Gillan disbanded the group soon thereafter, citing damage to his vocal cords. The rest of the band, upset about this sudden dissolution of their livelihood, sued Gillan, and they must have been even more annoyed when quite soon he was...Born Again.
