From piano-guitar duo album Searching For The Disappeared Hour this is extraordinary. Mary Halvorson's signature detunery and aching bluesy sense hard set against the strict avant garde atonal empathy of Sylvie Courvoisier who wrote the piece, Courvoisier's playing style at times reminiscent of Julie Sassoon. Recorded last year in a studio in Mount Vernon, New York the piece is both original and stimulating, these two formidable improvisers matching and fusing as spiky, oblique lines intertwine and the duo discover new shared spaces to explore and then inhabit.
