Mixology, the annual festival curated by the new music and new media organization Roulette, got off to a strong start last week with opening night performances by Pamela Z and Elliott Sharp, presented in collaboration with Harvestworks. Pamela Z demonstrated her use of gesture to control sound, which she produces with her own operatic voice as well as electronically. Elliott Sharp was a one-man noise band, playing both an amplified saxophone and a keyboard-based instrument while manipulating both on his laptop. The night ended with an improvised duet, in which Pamela Z played her iPhone like an ocarina.

Performances continued through the weekend and will resume tonight. Tomorrow’s program features Matthew Ostrowski, who will pick up themes of gesture and sampling with a new work titled “Patterns of Changing Light.” Mixology runs through May 30, concluding with a performance by downtown stalwart David Rosenbloom, whose piece Sound and Light I continues his thirty-year-long exploration of dense sonic textures with a more recent integration of video as the basis for an evolving score. The full program for the rest of Mixology can be found on Roulette’s calendar.
