The duo setting is ideal for intimate and intense dialogues, all quite left of center, but with sufficient discipline and maturity to make this a highly enjoyable and relatively accessible listen. Heberer's technique on the quarter-tone trumpet is nothing short of stunning. Listen for instance to his long circular breathing part on "345 Grand Street", with Okkyung Lee on cello, matching the continuous tone of the bowed instrument. The most extended techniques are used by Kaufmann on the beatiful first track. The duet with Eisenstadt is more fractured and power-driven with sudden changes of pitch, and with a clear blues-based tone, whereas his duets with the clarinet and the piano show a more lyrical side. On the last track, Heberer and Badenhorst exchange timbral explorations with playful interchange, while falling back on a quite solemn compositional backbone.
