Experimental music ensemble the Scratch Orchestra first got groovy in 1969 with the publication of their “draft constitution,” a founding document of open minds and curious hearts that produced groundbreaking sounds and innovative art. L.A. musicians re-create the collective's work with a performance of scores from founder Cornelius Cardew's 1972 book, Scratch Music, plus new works based on instructions in the constitution. After the music: a screening of Luke Fowler's 1996 Pilgrimage From Scattered Points, a profile of Cardew, and a panel discussion on radicalism and experimental art, with members of such collectives as Ultra Red and the Association for the Advancement of Creative Musicians.
