The 4th album from Japanese percussionist Seijiro Murayama and Parisian Jean Luc Guionnet, typically a saxophonist but here on pipe organ, presenting three live improvisations named for idiophones, instruments that creates sound by vibrating without the use of strings or membranes, with two improvisations at a church in Berlin and one at a church in Ljubljana, Slovenia.

Four recordings of subtle improvisation for saxophone & percussion, recorded for Radio Nationale Slovene in Ljubljana, and in the library of Jean-Paul Manganaro, Paris.
