This is one of the pieces we performed live at the April, 2015, Brewster House Concert series.  It is a duet between a Tocante and live computer-generated sound.  I played Tocante and Ivan Seng played the computer.  The computer sound was created in real time and used a series of ‘synthesizers’ operated by the choice of random number seeds.  This was a rehearsed piece that contains some improvisation within parts.
