Badlands was an American heavy metal band founded by former Ozzy Osbourne guitarist Jake E. Lee, former Black Sabbath members Ray Gillen (vocals) and Eric Singer (drums), as well as former Surgical Steel bass player Greg Chaisson.

After the first Badlands album, Singer was replaced by Jeff Martin. Compared to the sound of the members’ former bands, the sound of Badlands was more in a Led Zeppelin-influenced blues/hard rock vein.

The group lasted from 1988 to 1993 and released three albums. Badlands (1989) and Voodoo Highway (1991) were released before Gillen left and was briefly replaced by singer John West. Gillen’s death in 1993 effectively ended any hopes of reuniting the project. The album Dusk (a demo recorded in 1992–1993) was released in 1998 with then-recently deceased Gillen on vocals.

After touring with Ozzy Osbourne in support of the Ultimate Sin album, Jake E. Lee was fired by Sharon Osbourne. Lee set about looking for a charismatic front man with whom to launch a new band. He met Ray Gillen, a vocalist who had recently worked briefly with Black Sabbath. Within weeks, the duo had enlisted bassist Greg Chaisson, whom Lee had met during an audition for Osbourne’s backing band. Gillen recruited his former Black Sabbath bandmate Eric Singer to be the band’s drummer.
