A late and welcome arrival from the Matchless vaults. Phlegm captures AMM in their classic trio configuration, Eddie Prévost on percussion, Keith Rowe on tabletop electronics, John Tilbury on piano, recorded live at the Huddersfield Contemporary Music Festival, November 2015. One continuous hour-long piece, a setting closely aligned with the group's longstanding commitment to electroacoustic improvisation and one of the final documented performances of the trio.

By this stage AMM's language had been distilled into a near-silent, highly attentive practice in which conventional instrumental identities dissolve into a shared sonic field. Prévost articulates space and texture as much as rhythmic gesture, Rowe introduces fragile discontinuities and low-level interference, and Tilbury, often reduced to isolated tones, internal resonances and measured decay, anchors the ensemble through restraint rather than assertion. The music does not develop in linear fashion: it advances as a continuous act of listening, where events emerge, dissipate and reconfigure with extreme sensitivity to duration and presence, and silence functions as active material shaping the form of the piece.

The album takes its title from an extended coughing episode in the audience, initially impossible to ignore, eventually absorbed into the continuum of sound and listening, true to AMM's egalitarian approach to sonic phenomena and to a discipline in which the smallest inflection assumes structural significance. AMM disbanded in 2022; Phlegm stands as a distilled document of the trio's mature aesthetic, patient, immersive and unwavering in its commitment to collective attention and the primacy of listening. Essential.
