Norwegian saxophonist Kjetil Møster’s self-named jazz-rock unit released its first album, Edvard Lygre Møster, in 2013 and has moved through a number of line-ups and sounds since. While the Moog and Fender Rhodes of keyboardist Ståle Storløkken leant that debut a cosmic-jazz twinkle, subsequent releases replaced keys with guitar, touching on doomy, industrial rock and crunching prog-jazz with nods to King Crimson.

Møster!’s sixth album features the same personnel as 2020’s Dust Breathing, cementing a supergroup of the Norwegian underground: guitarist Hans Magnus Ryan of psych-rockers Motorpsycho, bassist Nikolai Hængsle of Elephant9, and drummer Kenneth Kapstad, formerly of Motorpsycho and the only member, other than Møster, to play on all their dates so far.

In the four years since Dust Breathing, Møster! have, however, evolved yet again. Math-rock virtuosity and bombastic overdrive have largely been jettisoned in favour of a mellower appreciation of the hypnotic properties of the groove. ‘Spaced Out Invaders Part I’ patiently builds a menacing riff over a thickly percussive burble, suggesting an infernal, rainforest Boléro. ‘Torsional Pendulum’ sits Hængsle’s bubbling bassline over a funky trip-hop break. And ‘Atmospheric Entry’ enjoys a kind of dubwise spaciousness. But Møster still knows when to turn up the tenor heat.
