The Berlin-based collective Takatsuki Trio of Rieko Okuda on piano, Antti Virtaranta on double bass and Joshua Weitzel on guitar & Shamisen are expanded to a Quartett in two extended live sets at Berlins' Kuhlspot Social Club in 2020, first in an expansive set with trumpeter Axel Dorner, and then an intensely active set with tenor saxophonist & clarinetist Tobias Delius.

An extended improvisation performed live at Kuhlspot Social Club in Berlin from the Takatsuki Trio of Rieko Okuda on piano, Antti Virtaranta on bass and Joshua Weitzel on guitar & shamisen (a 3-stringed traditional Japanese instrument), captured at their monthly series expanding the trio to a "Quartett" for fresh perspective, here with alto saxophonist Silke Eberhard.

The core of the German free improvising Takatsuki Trio is Rieko Okuda (piano, viola, &c.), Antti Virtaranta (bass), and Joshua Weitzel (shamisen, guitar), who, while touring, ask a guest from the area they're performing in to join them, here inviting tenor saxophonist Matthias Schubert in Kassel, Germany, and in Wiesbaden, Germany inviting saxophonist Dirk Marwedel.

The Berlin-based electroacoustic Red List Ensemble founded by cellist Guilherme Rodrigues in a studio recording of the 3-part "Scope", improvised music created in real time using extensive techniques to create and raise tension in a game of contrasts, exploring orchestration in micro-groups through organization of surfaces that are opposed in terms of timbre and sound texture.

Two distinct improvisation from the trio of Japanese musician Rieko Okuda on piano & viola, Finnish musician Antti Virtaranta on double bass, and Russian musician Girilal Baars on voice & objects, the first with Baars primarily focused on free vocals in a Phil Minton-esque mode, the second all instrumental with Baars performing on "old wheel".
