Watch: Justin Vernon, Bryce Dessner And So Percussion's 'Music For Wood And Strings'

Here's music with a great backstory and unique evolution. "Music for Wood and Strings" began with an idea from Bryce Dessner who not only conceived of the music but invented the instrument the music was played on. As So Percussion's Adam Sliwinski has been playing these "chordsticks" while they perform "Music for Wood and Strings" and explains that "chordsticks are a hybrid grew out of Bryce watching us play the chordsticks. He decided that playing string instruments didn't prevent us from still playing intricate rhythmic patterns! Aside from one string on the bass instrument, none of the chordsticks have frets — each chord is fixed and the musical texture is achieved by bouncing notes around the ensemble. We play them with plain #2 pencils, which started as placeholder beaters but ended up doing the job well."
