"Marblehead" was orginally created for choreographer Daniel Burkholder. 
The only information he gave me about his dance was its total length, and
that for props he would be using a chair and an enormous glass bowl full
of marbles.  So with that I decided to base the music entirely on the
sounds of marbles.... The title comes from the comment of a friend
discovering me one evening throwing marbles in and on the contents of my
kitchen, in search of interesting sounds.
