//  In cellist and composer Cris Derksen's solo show, classical, Indigenous and urban elements combine: you may get the propulsive pounding of powwow music, the head-nodding rhythms of a hip hop track, the metronome thumps of a techno mix, or all three in the same song. Her instruments are loop pedals, a drum machine and, of course, the cello: its melodies are plaintive but catchy, growing in number as the song progresses. These hooks repeat like echoes, part of a thick mixture yet distinct within it.
