Percussionist Tanguay, and trombonist Walsh are no less ambitious on Midi tapant, blurring the lines between spontaneous music and formal composition. But while Callas was a dazzling technical feat, Midi tapant is far lower key affair. Beginning with minimalist drone patterns, the two then drop in manipulated world music samples like gamelan and chanting voices, as well as big band sounds, against which Tanguay and Walsh play and create a new sonic world that is soothing yet exhilarating, searching yet knowing, exotic yet familiar. What is real and what isn’t, Midi tapant doesn’t answer that question because it doesn’t have to. In the end, the answer begins where it ends in the listener’s imagination.
