Judas Priest-Turbo (1986)

In 1986, Judas Priest showcased their experimental side with the release of "Turbo", a controversial yet successful album where they first used synthesizers and embraced (albeit quite subtly) heavy pop. At the height of their success, Rob Halford and company dared to flirt with the styles that, at the time, most rivaled hard rock and heavy metal: the glamorous and commercial sound of American glam metal. Much like Iron Maiden did during those years, synthesized guitars are used elegantly, at least in tracks like the monumental "Turbo Lover", which would become an instant heavy metal classic. "Locked In" and "Private Property" follow a similar path, featuring the immense talents of K.K. Downing and Glenn Tipton on guitars and a driving rhythm section comprised of Dave Holland and Ian Hill. However, there are also glimpses of the usual Judas Priest sound with the ironic "Parental Guidance", the carefree "Wild Nights, Hot & Crazy Days", and the heavy rock of "Reckless". Despite being maligned by many of their more orthodox fans, "Turbo" is the album that best balances raw, powerful heavy metal with the rock/pop of the 1980s.
