New releases last four weeks: Experimental/Electronic

Review: Einsturzende Neubauten's description by label Potomoak - as a band that constantly evolves - is accurate enough. Over forty years on from their debut album Kollaps in 1981, Rampen appears as the latest and most unruly incarnation of their sound yet. Here, Blixa Bargeld, N. U. Unruh, Alexander Hacke, Jochen Arbeit, Rudolph Moser and Felix Gebhard present their least predictable and conventional sides: APM is described as alien pop music; the songs therein have been specially crafted not only for our universe but for every adjacent parallel universe to ours, with every slight multiversal variation in humanity's collective tastes held firmly in mind. The album fully lives up to its billing as anti-pop as alien pop, its challenging twists and turns fully sating the difficult whims of society's outcasts and cosmic punks.

Review: Something of ground-breaking album on its initial release in December 1994, ISDN is one of Future Sound of London's most name-checked sets. It's effectively a re-edited and rearranged collection of live recordings - jammed out tracks that were initially broadcast to the world via ISDN links to clubs and radio stations, which FSOL brilliantly moulded into a mind-mangling journey through IDM, trip-hop, proto-big beat, dub, ambient, found sounds, field recordings and wayward electronica. To celebrate the album's 30th birthday, it returns as a two-disc set, freshly 'amalgamated and re-sequenced' by FSOL to include material from both previous editions of the album. It is, then, a kind of 'definitive version' of the LP, and one that still sounds as joyously weird, trippy and psychedelic as it did first time around.

Review: In recent interviews, Justice explained that fourth album Hyperdrama - the wildly successful French duo's first for seven years - was born out of the idea of getting elements of disco, funk and electronic music to "fight with each other" (rather than smoother co-existence). Given the forthright and sometimes abrasive nature of their work, it's an idea in keeping with their career to date. Musically, what we get is a mixture of their usual electroclash and rave-inspired riffs and motifs, and basslines, strings and other instrumentation rooted in black dance music of the 1970s and '80s. When the fusion lands - as it does much of the time - it's a unique and thrilling fusion. For proof, check Tama Impala hook-up 'One Night/All Night', the Italo disco/jazz-funk/electro-house fusion of 'Incognito', and the wonderful slow-boogie mutation 'Saturine'.

Review: Few bands have sidestepped expectations as cannily as Mount Kimbie. Initially a duo but now expanded into a quartet, the British band has previously excelled in mixing, matching and fusing a wide range of experimental and left of centre electronic music influences. On The Sunset Violet, their first full-length as a quartet, they've shifted sonically once more, leaning into their indie-rock influences on a set recorded in California. The latter aspect - and the impact of being surrounded by sunshine and desert - is reflected in the warmth and haziness of the sound, which draws on the layered vocals and guitars of vintage shoegaze while also reaching for more familiar aspects of the band's previous experimental electronic sounds (for proof, check the ghostly musical vision that is King Krule collaboration 'Boxing').

Review: Analogue synth spooks rejoice, Pye Corner Audio is back with further explorations of the sweet spot between nostalgic fuzz and circuit-borne futurism. Ghost Box is a spiritual home for Martin Jenkins' flagship project, and he continues to edge out the scope of the Pye Corner sound without derailing the fundamental atmosphere. On The Endless Echo, warm, pulsing melodics set to eerie keys abound, and there's a fine balance between gorgeous ambient atmospheric pieces and sinewy, danceable rhythms, but Jenkins manages to sound fresh and inspired even while reliably holding true to the overall project aesthetic.
