Swedish contrabass clarinetist Christ Bothen in six extended works, the first and third disks a series of solo works using incredible technique and concentration, the 2nd disc a large work in an ensemble with fellow deep reedists Hans Koch & Per Texas Johansson, double bassist Vilhelm Bromander, pianists Kristine Scholz & Tisha Mukarji, and a spectral narrative from Sofia Jernberg.

1992 live performances demonstrating masterful freedom in improvisation, recorded while on their first tour as a duo after working together in larger ensembles, from Hans Koch on clarinet, bass clarinet and tenor & soprano saxophones, and Paul Lovens on drums, cymbals, gongs & musical saw, in four live improvisations from Bulgaria presented in the order recorded.

A unique pairing of reeds, piano and spinet captured live at Le Singe Club in Biel, Switzerland in 2018 between multi-reedist Hans Koch and keyboardist Jacques Demierre, a wild ride from frenetic interaction to introspective experimental, both using unusual techniques and Demierre playing inside his keyboards, a truly excellent and thrilling concert.

A dynamic set of wind and object improvisations from multi-reedist Hans Koch, using extended techniques to elicit a diverse and astounding range of sounds from his instruments, and Thomas Peter creating indescribable sound on amplified objects and live electronics.
