In Tokyo, the concert of his works was delayed by the events in March last year so I had an opportunity to hear it last night at Tokyo Opera City, an extraordinary, relatively new concert hall. Here's a slightly blurry iPhone pic (gomen nasai) -
You'll notice a large thundersheet on the left side of the stage. There is also one on the right side as the first piece was for a double orchestra. Later they brought out yet a third thundersheet for another piece. Gotta love those thundersheets!
The concert program included -
Berceuse for orchestra (1967)
Libro notturno della voci for flute and orchestra (2009)
Archeologia del Telefono - concertante for 13 instruments (2005)
Studi per I'intonazione del mare with voice, flute quartet, saxophone quartet, percussion, ensemble of 100 flutes, and ensemble of 100 saxophones (2000)
All in all a concert of very interesting and unique work... Great to hear - a rare opportunity.
