Technical Ecstasy continued the band's separation from its signature doom and darkness that had been such a trademark of the band's early career. While the album's lyrics dealt with topics such as drug dealers, prostitution, and transvestites, the music itself was seldom dark, and tracks like "Rock 'n' Roll Doctor" and "It's Alright" (the latter sung by drummer Bill Ward—a decision supported by Ozzy Osbourne), were very different from Black Sabbath's earlier recordings. Also, the band continued experimenting with keyboards and synthesizers more so than previous albums. The track "She's Gone" features orchestrations.
Osbourne left the band briefly following the release of the album. He would eventually rejoin for the follow-up album, Never Say Die!.
The UK release had a two-sided lyric/credit-insert.
"Gypsy", "Dirty Women", "Rock 'n' Roll Doctor" and (briefly) "All Moving Parts (Stand Still)" were played live on the supporting tour.found here: http://en.wikipedia.org/wiki/Technical_Ecstasy
