an appropriate introduction to an excellent composer. coming from IRCAM (like Saariaho), Stroppa uses multitracking/software/ electronics in these pieces to generate and refract resonances not available on the instruments (piano; string quartet) to create "aural paradoxes," stacks and swarms of harmonics that, in concert, become an almost palpable 3-dimensional wall of sound. basically, he's using his own frequency models to physically shape both the actual sounds being created by the performers as well as the potential sounds residing within the instruments themselves, which kind of blows my mind. even in moments of silence, you can hear the ghost notes bouncing off the body of the piano or strings and resonating throughout the performance space, like conjuring music from thin air.
