Minimalist composer Max Richter hears opportunity when a cell phone rings.
"Why is is it that the ringtone medium has so far been treated as unfit for creative music?" he wonders.
In his "24 Postcards" suite, Richter has composed short pieces designed to be used as cell phone ring tones. He envisions a performance in which the audience, having received text messages from the composer, "performs" the work. Very interesting!
Go to the 24 Postcards site to listen to the ring tones. They're very inspiring, and further push what I'm now recognizing as a new creative discipline: the creation of visual art or music intended for an audience using a specific piece of digital hardware, like a phone, or a computer.
