No more than two dozen patrons have filed into the upstairs concert hall of Montreal’s La Sala Rosa for an evening of live jazz. Among the dedicated few sits Mark Crawford, a beer in his right hand and a focussed yet unassuming countenance on his face. Positioned front and centre, Mark is preparing a medium-sized microphone stand that is wired through a pre-amplifier, digital to analog converter, and power supply into his digital recorder.
