Two reeds, a cello and a signal processing instrument in this live electroacoustic improvisation session captured at Petersburg Art Space, in Berlin, Germany between cellist Guilherme Rodrigues, saxophonist Harri Sjostrom on soprano & sopranino using selected mutes, clarinetist Floris Floridis and electronic improvising legend Lawrence Casserley.

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".
