This is a long CD, so it’s also a double LP: a live Los Angeles set with an incredibly hushed audience and an ambient aural quality that can be tasted.

Four tracks, each between 17 and 24 minutes, allowing maximum extension, maximum repetition and maximum listener savouring. These four players investigate heightened sensitivity over great distance, aided by various electronic and sampling treatments, and with half the membership stressing the word ‘amplified’, for their acoustic instruments, as this is another subtle tool of tonal manipulation.

And there are also gradual tunes, slowly feeding into the senses. ‘Freakadelic’ is the best cut, quietly pursued by ‘Easy Way Out’, both over 20 mins in length. Parker governs a curious form of incremental loping towards an insular ecstasy, Johnson often with harmonised tonality, like a ghost-groove afterlife, zig-zagging across the linear flow. The altoman offers unexpected phrasing in his relationship to the measured rhythms, but all members are responsible for slight skips in the pace, as they softly corrupt the march. Later, cymbals are heard in fresh detail, while bass paces the room lightly, towards the shimmering coast.

Brushes make skimmed metal whispers, Parker applies sharp string pressure, and dainty alto stitches through the relaxed skin-tension of the bass. The set closes out with hints of dub, the slightly sped-up saunter of ‘Chrome Dome’ providing the greatest density of activity. This beautifully-captured gig is a sheer classic of restraint and drip-feeding aural nourishment.
