Beginning with an 8-member vocal incantation led by Taylor himself, this incredible reunion concert between pianist Cecil Taylor and drummer Sunny Murray was recorded by the FMP label in 1996 at the Total Music Meeting in Podewil, Berlin, an incredible display of pyrotechnical playing with an exultant excitement through three "sector" improvisations; extraordinary!

A series of trios and duos between Italian vibraphonist Sergio Armaroli, trombonist Giancarlo Schiaffini and saxophonist Harri Sjöström performing on soprano and sopranino, the three developing a compositional language based around phrases and propositions applied toward the creation of events through notes and timbre intended to create moods and sensations.

A live recording of insightful collective improvisation recorded in 2019 at the Moers Festival in Germany, from Harri Sjostrom on soprano saxophone, Achim Kaufmann on piano, Adam Pultz Melbye on double bass, Dag Magnus Narvesen on drums, and Emilio Gordoa on vibraphone, in an extended exploration of subtle hues through effortlessly intense and inventive interaction.

Bringing together a wealth of experience in contemporary improvised music, Berlin-based cellist Guilherme Rodrigues and soprano and sopranino saxophonist Harri Sjostrom developed these 12 pieces, combining and contrasting their instruments, at times seeming to complete each other's phrases, in a remarkably sophisticated and virtuosic "Treasure".
