Contemporary compositions for solo percussion are not exactly commonplace, neither in academic contemporary music nor in free jazz, improvisation or DIY experimental contexts somewhere in between. Canadian snare virtuoso Ryan Scott, a friend and occasional collaborator of the Canadian string quartet Quatuor Bozzini, consequently gathers the compositions on 21st-Century Canadian Snare Drum (Collection QB, 13 February) from all corners of the scene and beyond. The often central, but not always dominant, instrument is a military-style snare drum, from which Scott has, however, banished all martial elements. It is impressive what works here, and interesting what does not — and what a wealth of timbre can be drawn from purely percussive sounds.
