Originally written for orchestra, Phill Niblock’s Disseminate (1998) and Baobab (2011) were arranged by the composer specifically for the Bozzini Quartet, or rather, for ‘multiples’ of the Quartet: twenty different tracks are mixed in each piece — twenty different instruments, the equivalent of five string quartets. The music is essentially a work on the shifting nature of overtone patterns that arise from acoustic instruments. As composer Robert Ashley convincingly argued, these pieces inscribe themselves in the “hardcore drone” scene of American electronic music: “Niblock [brings] the orchestra into the electronic world.” For Disseminate and Baobab, Niblock scored a distinct set of microtonal intervals, and the players are indicated how sharp or flat they should play. But a certain sense of range is given around each chromatic pitch, so that every bow stroke partly determines the microtones.
