The album features a single hour-long track, titled "Aether", performed by Chris Abrahams, Lloyd Swanton and Tony Buck.

Allmusic reviewer François Couture stated "Aether is simply their best release, a wonderful album that breathes at its own pace.

Though they're playing with just a single chord, subtle nuances, additions and subtractions tease out new beauties within it throughout the piece.

Aether's 64 minutes pass by with the ease of seconds but each are as elemental as the phases of the moon.

[3] On The Quietus Nick Southall called it "their ruminative, ambient masterpiece, as minimal and repetitive as Basinski's Disintegration Loops but somehow more alive, unburdened by the weight of association.
