Crosstalk is a "duet for pianist and piano". The performer plays a piano part live (on a MIDI-enabled piano) from notation, and the MIDI output is sent to a laptop running Max MSP. The Max patch running on the laptop analyzes the realtime input and uses it to trigger the second part of the duet, which is played on another (virtual) piano.
This is a unusual piece for piano and electronics, written for Sebastian Berweck. The electronics are based of recordings of shovelling mud and the piano part involves a variety of transcriptions. Here's the original program note:
“Distance, no matter how close the object may be.” – Walter Benjamin
