The beautiful, lofty interior of the lovely St. John in Hackney church in Clapton was a fitting location to drink in the subtle, gentle tones of both these heavyweights of ambient music. Their sets were considerably different (and I should imagine that Helm - whose opening performance I sadly missed - also served up something wildly at odds with what came afterwards), but both reverberated around the hall, textures seeming to drift off the walls and out of nooks and crannies organically, meaning even the quietest moments in Basinski’s rendition of ‘Nocturnes’, from his recent album of the same name, were loaded with a palpable physicality.
