Recording in Altes Wannenbad Gera, in Gera, Germany, an ensemble of performers associated with Ensemble Open Music Gera and Ensemble Zeitkratzer perform James Tenney's work exploring concepts of tuning systems, sound/noise, consonance/dissonance, sound/silence, and organisation of time, in three pieces that use a climax-oriented form Tenney refers to as "swell pieces".

Jason Kahn developed these graphic scores, commissioned by the 2012 now NOW Festival in Australia, to push these specific players into situations outside of their comfort zone, as heard in this double LP which includes copies of the score plus notes and interviews.
