*Edition of 200* Minimalist Chicago trio return to Entr'acte with a mesmerising 40 minute study of whispering keys and crackling lower case noise. But don't get it twisted - this is not some beige modern classical, nor is it a rough copy of Basinski's 'Disintegration Loops' - it's perhaps best compared to a location recording of Morton Feldman duetting with an industrial air vent at midnight in a breezy and secluded location. The first quarter of the piece is used to shape the surroundings, an ether of wispy drones and distant, slowly modulating tones before the keys make their incredibly modest appearance, remaining a tantalising yet intangible presence almost drifting forth as though carried by the breeze. The proceeding 30 minutes evolve with incremental stealth, keys hover on the brink of silence, flickering like candles against a breath of wind as the near static atmosphere incrementally builds with the  imperceptible developments comparable with an Eliane Radigue piece or the microscopic focus of a Jakob Ullmann composition. Quite simply, barely anything happens, but it's a totally engrossing experience all the same.
