he depth and ease of the quartet's rapport is evident from the first moments of the opening title-track. Berthling's resonant upright bass locks into a head-nodding ostinato that makes sensitive use of a prominent end-of-phrase rest, opening spaces through which Werliin's continually shifting statements of the pulse shine through. Having worked together in various groups for many years, Berthling and Werliin are masters at playing subtle games of difference and repetition, creating a driving rhythmic flow animated by perpetually changing details: here, you can never step in the same groove twice. Weaving through it all is Ambarchi's now-signature Leslie-cabinet guitar tone, sounding out long chords at times strikingly close to a Hammond, while also creating intricate cross-rhythms through the play of his tremolo modulations against the bass and drums.
