Any keen follower of vintage minimalist drone will already be familiar with the meticulous tonal landscapes of Eleh from the series of limited LPs issued from the Important camp over the past year or two. True to the form of that series this new split release is already sold out at source, coming housed in the same luxurious sleeve design and pressing quality that helped shift all those units previously. Authenticity is the key to Eleh's success, and it's a sound that calls upon a heavy dose of La Monte Young and the use of classic modular synthesis and tube-powered oscillators. In previous instances the end product has been characterised by low-end tones and the sheer, bludgeoning heaviness of static bass, the piece on this LP serves as an especially fine example of that, but goes some way to expanding upon the established Eleh sonic language: 'Fading Spectrum Of Darkness' deviates slightly from the intense stillness of previous outings, with a more pronounced sense of texture characterising the analogue hum - there are some ripples on the surface thanks to some LFO interventions carving out a deep shimmer, leading into a final third that reveals the true gravity of the sub-sonic drone that lies beneath. This is the kind of bass most producers would kill for, and on this heavy vinyl pressing it's a real boneshaking joy. The Sun Circle side is somewhat more conventional, opting for a psychedelic infinite-chord approach, with plenty of discernible instrumental components peering from beyond the loud, droning glare. It's a promising Important debut for the mysterious new artist, but it lacks the uncompromising, disciplined brilliance of its Eleh counterpart.
