Christer Bothen / Oren Ambarchi - Serpentine Christer Bothen / Oren Ambarchi

After the wild Afro-jazz fusion of Trancedance (reissued as BT118) and the meditative solo Christer Bothén Donso n’goni (BT133), legendary Swedish multi-instrumentalist Christer Bothén returns to Black Truffle as part of a dream quartet completed by the three members of Ghosted: Oren Ambarchi (guitar), Johan Berthling (bass) and Andreas Werliin (drums). Recorded at a rustic studio built by Werliin and Hans Fredriksson in the sylvan surrounds of Hamburgsund, Sweden across a few days in September 2023, Serpentine offers up four generous slices of hypnotic repetition and shimmering resonance, cut through with wild bursts of Bothén’s bass clarinet.

The 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. When Bothén enters five minutes in, the growl of his bass clarinet at first works deep in the collective brew, carving off brief staccato phrases and twisting them into fragmented melodies. As he moves into the instrument’s higher registers, Bothén’s playing becomes wilder, twinning with Ambarchi’s guitar in shimmering arcs like a 21st century update of the Garbarek-Rypdal pairing immortalised on Sart.

Each of the four pieces explore different possibilities of a shared language. On ‘Antigorite’, another hypnotic bass riff emerges gradually from an atmospheric haze, eventually developing into a frenetic rhythmic workout propelled by Werliin’s cowbell. Berthling sits out for ‘Lizardite’, while Bothén moves from bass clarinet to the Donso n’goni, the sacred Wassoulou hunter’s harp he has studied for half a century; the resulting performance streamlines the approach heard on other tracks into pure modal propulsion, sparkling with harp-like arpeggios from Ambarchi’s guitar. On the closing ‘Chrysotile’, the bottom drops out, leaving a swampy, churning mass of wavering organ-like chords, roaming bass runs, and distant toms, over which Bothén floats bass clarinet figures by turns bluesy and abstract, the whole thing landing somewhere between classic ECM and the most blasted freeform moments of early Amon Düül II. Bearing a delicate calligraphic abstraction by Bothén on its cover and beautiful documentation of the recording sessions on its inner sleeve, Serpentine is a powerful reminder of the magic that can happen when inventive musicians just get together and play.
