A sense of both lightness and weight drawn from Portuguese viola player's Ernesto Rodrigues' 18-piece String Theory, in a large and detailed improvisation using an incredible array of string sources, including viola, harp, violin, cello, viola da gamba, double bass, classical, acoustic and 12-string guitars, mandolin, zither, harpsichord, and piano.

Andrea Belfi (percussion), David Grubbs (guitar), David Maranha (organ), and Pete Simonelli (voice) perform "Ten Intrusions", following the model set by Harry Partch's 1949-1950 composition "Eleven Intrusions".
