Review: When it comes to crafting memorable electronica, Malka Spigel and sometime Wire member Colin Newman are old hands. The duo released their first album as Immersion way back in 1994. This fourth full-length follows on from 2016's critically acclaimed Analogue Creatures Living On An Island and shares some stylistic similarities. Like that set, Sleepless contains numerous nods to 1970s krautrock (particularly Tangerine Dream and Popol Vuh), alongside detectable looks in the direction of laidback ambient techno, shoegaze, tactile downtempo grooves, melodic Balearic moments and the kind of hybrid analogue/electronic soundscapes that defy easy categorization. Throughout, the duo push mood and melody to the fore; as a result, the album is deliciously soft-focus and dreamy, even at its' most full-throttle and up-tempo.
