There are two other reviews of this record, both saying its underated, but then only giving it 4 stars? Don't be shy lads, there's nothing wrong with Tech Ec at all. The band had been experimenting with new sounds and production ever since Sabbath Bloody Sabbath, and whilst I accept the band were in meltdown with Ozzy's behaviour, they still came up with another great LP. More great riffs and fantastic songs with Ozzy's finest ever vocal performance. Songs like Rock'n'Roll Doctor were a little more commercial, but no more so than Am I going Insane from the previous release, Sabotage. You Won't Change Me, Gypsy and Dirty Women are chock full of everything you'd expect from Sabbath - great, great songs, and its sad that they never get played live. Even the inevitable ballad, She's Gone is one of the most amazing things they ever did. If they'd wanted to cash in, this would have topped the charts as a single, and would be talked about in the same hushed tones as Nilsson's Without You. It's just a great LP, and why it ever got such a bad press is beyond belief.
