The latest release on Cheltenham’s burgeoning (and eclectic) Byrd Out label comes from Gdansk-based electro-acoustic quartet Siema Ziemia. The name roughly translates as “Hey earth – what’s up?” and reflects the band’s belief that electronic club music has a link to primitive cultures and a closer contact with nature.

Their commitment is to make an improvised electro-acoustic music that recreates the highly organised structures of electronic dance music. They achieve this impressively by various looping strategies and a well-tempered use of electronic tones and textures in ways that range from the basic minimalism of ‘See You On The Other Side’, a straight-to-the-dancefloor House number to the hard-bop infused dubstep of ‘KTDT’. Across its 12-minute length the epic ‘All Those Moments’ uses a wilfully leaden bass line to drive a sequence of tonal shifts that include suave acoustic sax, dirty cosmic guitar, dubbed-out House beats and remorseless hardcore drumming to the end.

It is all quite skilfully done, with a gleeful sense of respectful pastiche that never tips over into cliché, with moments of raw power reminiscent of The Comet Is Coming. The best moments come when you feel their improvisation most unleashed as in ‘We USed To Cry’ which takes a gentle waltz melody from quietly harmonised sax to a scrawling sax-vs-synth bridge and a smashing six-time big beat exposition before returning to that genteel opening theme. It’s smart stuff, full of controlled energy.
