Invited by Pioneer Works' for their 2013 winter party, Clara Claus created a fifteen-minute Graphic Score in three movements for two musicians; Gaspar Claus (cello) and Mitchell Yoshida from the band Edward Sharpe and the Magnetic Zeros (Sample machine). Two colors were used by Claus to define the different parts for the musicians to read: black for Gaspar Claus and red for Mitchell Yoshida. For the live performance the two musicians engaged in an improvised musical dialogue, reacting to the video of the Graphic Score.
