»Pressure Chords« is the first joint album by composer-performer John McCowen, trombonist Weston Olencki and cellist Lucy Railton. McCowen’s composition is based on the spectral analysis of contrabass clarinet multiphonics, and the tuning system corresponds with the overtone spectrum of McCowen’s instrument. The trio adaptation of »Pressure Chords« presents itself as an exercise in both patience and intensity, slowly building towards an expressive finale. Across its 34-minute runtime, restrained minimalism slowly gives way to maximally affective sonic force.

McCowen, Olencki and Railton first shared the stage for an improvised session at Berlin’s KM28. McCowen realised that he found two capable partners for creating orchestrations of his works for the contrabass clarinet. Olencki, who also contributes field recordings to the album, has worked across different genres and traditions, while Railton has made a name for herself as a composer and improviser as well as a performer of Just Intonation music. »Weston and Lucy both have immense experience performing and composing music outside of equal temperament, so it seemed like a perfect situation,« McCowen says.

The trio first presented »Pressure Chords« live at Berlin’s Morphine Raum in 2023 before recording a studio version with Adam Asnan in the following year. The recording - mixed and mastered by Albert Finnbogasson in Reykjavík - elegantly captures the multi-layered tonal and sonic qualities that the musicians so carefully explore. As a result, their performance doesn’t so much invite but necessitate deep listening—time passes differently on and with »Pressure Chords.«
