Martin Arnold  Flax Kerry Yong, piano Another Timbre   Martin Arnold’s solo piano work Flax has a sad backstory. It was originally commissioned by the abundantly talented new music pianist Philip Thomas, who shortly afterward became seriously ill and was unable to premiere the work. Kerry Yong performs the piece in his honor on an Another Timbre CD. The piece was already well underway when this transpired, but one cannot hear the considerable poignancy and elegant gracefulness of Flax without connecting it to Thomas’s loss of health.    Arnold is a Canadian composer whose work is influenced by Morton Feldman
