Ferneyhough's Bone Alphabet

An interesting video of Ferneyhough talking about how to play the beginning of his piece Bone Alphabet, also I've posted a performance of the piece in the video below that by Morris Palter (I can't vouch for the accuracy of the performance, I don't have the score, or the 'chops' probably but it sounds good to me anyway apart from the usual camcorder sound issues)
