The quality of this music may be heard in the way it simultaneously invites and rewards different kinds of listening. It can be heard as both responsive dialogue and as an assembly of layers. Marco von Orelli exploits the particular clarity of his sound - whether open or muted - to provide a kind of linear focus, while Keller can generate an orchestral sweep at the piano and Suter sometimes brings a drama that resembles the energy of taiko drums; however, all three are adept at making music at teh granular level, creating continuous sound at the leve of the particle, suggesting the atomic make-up of sound itself, the grain of consciousness.
