Compositions for percussion from Berlin drummer and accordionist Hannes Lingens (Musaeum Clausum, Antoine Beuger, Lucio Capece, &c), composed over six years, each using a restricted set of materials, instrument or instrument type, Lingens performing solo, and as a duo and quartet using overdubs, employing microphone techniques for detail and ambiance.

Musaeum Clausum is a French-German trio that features Louis Laurain on cornet (Die Hochstapler, Umlaut Big band, ONCEIM), Hannes Lingens on drums (Obliq, Konzert Minimal) and Sebastien Beliah on bass.(Un Poco Loco, Ensemble Hodos, Umlaut Big Band), in an album of patiently developing improvisation giving each player freedom and flexibility within a composed framework.

Three works from Canadian composer Chiyoko Szlavnics, two electroacoustic compositions incorporating sinewaves, one with a saxophone quartet and the other with two accordions, two flutes and two percussionists; and a string trio of long sustained tones and slow glissandi.
