I just watched Edmar Castaneda on NPR's Tiny Desk podcast. He does things with the harp you would not believe. Well worth a look.

In the same series is Low Anthem doing interesting things with mobile phones. Take two mobile phones, call one from the other, hold close while whistling and modulate the feedback. Never seen that before. Feedback for the 21st century.

I really like these NPR podcasts, they're acoustic and a bit folky, and it's great to see real musicians up close. Could we see a similar thing from Words Towers please? Word Unplugged? Softly Sung?
