Danish saxophonist Mette Rasmussen and US drummer Chris Corsano have already recorded together a couple of times – on their previous duo date, All The Ghosts At Once, in 2015, and with American high-energy tenor-man Paul Flaherty for 2016's Star-Spangled Voltage – which means they've spent enough time together to work out a joint vocabulary. In some ways, the spark that ignites them is fanned by stylistic contrasts and nuances. As he's shown in his work with Rodrigo Amado, Akira Sakata and others, Corsano needs little encouragement in whipping up a storm: he's a thrillingly physical player who effortlessly crashes around the whole kit in a furious boom and clatter. Yet, he's also a master of control, capable of quietly seething ferocity. Rasmussen largely avoids obvious signifiers of intensity, favouring broad fanfares with a high, wide vibrato or perilously tottering phrases that slide around like a drunk on ice. The two come together neatly in more meditative moments: Corsano's tolling gongs eliciting a delicate, underblown trill, or the snare's drill-like precision rattle matched by seesaw sputters. At one point, Corsano even breaks out a slide clarinet, sketching fragile, alien calls that overlap with Rasmussen's gauzy harmonics. They're full of surprises.
