The first album from the Japanese improvising quartet of electric guitarist Kazuhisa Uchihashi (Altered States), cross-media violinist Keisuke Ohta, bassist Shinobu Kawai (Yoshihide Otomo Special Big Band, Akira Sakata) and drummer Akira Sotoyama (Tipographica, Koichi Matsukaze Quartet), in three avant jazz improvisations captured live at Knuttel House in Tokyo.

Describing their improvisation as a chemical reaction of positive and negative ions, the central trio of the ensemble Skein--Achim Kaufmann (piano), Frank Gratkowski (winds) and Wilbert de Joode (bass)--are heard in this incredible 2018 concert at Konfrontationen Festival as a septet with Tony Buck (drums), Richard Barrett (electronics), Liz Allbee (trumpet) and Uchihashi Kazuhisa (guitar).

21 wild rides from the fully improvised duo of guitarist Kazuhisa Uchihashi on guitar & effects, and Tatsuya Yoshida on drums, voice & sampler, two CDs from four separate concerts at Japanese venues Akihabara Goodman in 2012 & 2014, Kichijoji FOXHOLE in 2014, and Okubo Hikarino-Uma in 2017; intensely exciting and magnificently masterful improv instrumental rock.

The 4th improvisation release of drummer Yoshida Tatsuya (Ruins, Koenji, &c) and guitarist Uchihasi Kazuhisa (Altered States) is a DVD audio release presenting 36 remarkable live tracks from 6 concerts recorded 2004-2012.
