After mentioning Clock DVA’s Thirst (1981) a couple of days ago I’ve been playing the album together with Pow-Wow ever since. 4 Hours was Thirst‘s accompanying 7-inch single, a marvellous slice of rumbling post-punk angst. The B-side, Sensorium, includes the words “Uptown apocalypse” among its lyrics, a phrase that’s also the title of the second track on the equally marvellous Music For Stowaways (1981), an instrumental album by the post-Human League, pre-Heaven 17 offshoot British Electric Foundation. This isn’t a coincidence; the latter number was co-written by Clock DVA’s Adi Newton, and features him playing guitar and synth, Newton having been in The Future with BEF’s Marsh & Ware prior to the formation of Clock DVA and The Human League. And to further complicate this tangle of Sheffield connections, 4 Hours was reissued in 1985 in 12-inch format on Cabaret Voltaire’s Doublevision label. I bought almost all the Doublevision releases but this was one I missed. (Was the title of Cabaret Voltaire’s Sensoria derived from Sensorium? Maybe…)
