Tod Machover invented the hypercello, which, briefly, uses IT to extend the cello's possibilities to respond to the physical gestures of the player. He wrote
Begin Again Again for solo hypercello and Yoyo Ma recorded it here. It is very congenial modernism, and Ma playing it is totally consistent with his conservative but modern tendencies (think The Silk Road Ensemble.) As far as I know Marr never recorded it, here it's Matt Haimowitz. This is modernism that your granny will love.
