Koboku Senjû has been played on NTS shows including Slow Hand Clutches, with Alt Starter Med Regn first played on 25 May 2018.

Tetuzi Akiyama, guitar Toshimaru Nakamura, no-input mixing board Martin Taxt, tuba Eivind Lønning, trumpet Espen Reinertsen, tenor saxophone + flute Koboku Senju, meaning something like «Selection of Dead Trees», is a continuation of the music developed on the album with the same name, 'Varianter av døde trær', released on SOFA in 2008. Since then, the ensemble has performed numerous concerts in Japan and Europe, finding a particular way of making music together. Their new release 'Selektiv hogst' sees the former quartet of Tetuzi Akiyama, Martin Taxt, Eivind Lønning and Espen Reinertsen joined by the no-input mixing board of Toshimaru Nakamura, who is adding yet another level of timbral ambiguity to the group, creating a rich ensemble sound.

Akiyama and Nakamura have both long been two of the leading improvisers from the Tokyo scene, and Lønning, Reinertsen and Taxt, are three young and active improvisers from Norway with an increasing reputation for their adventurous yet mature musicality.

"Japanese-Norwegian quintet Koboku Senju follows a calm through-line across turbulent free improvisation, finding austere and meditative beauty in a profusion of sonic details and textures that easily could've been dizzying … The performances are beguilingly rich and uncategorizable, and Selektiv Hogst is easily the best free-improv recording I've heard in years."
