The fourth disc in the Canadian Composers Series features the music of Chiyoko Szlavnics. The CD contains three works, two of which use sinewaves in conjuncton with acoustic instruments. The title track ‘During a Lifetime’ is written for sinewaves and saxophone quartet, an instrument on which Szlavnics herself used to perform. The final piece, ‘Reservoir’, is composed for sinewaves and an unusual instrumental octet, including two accordions, two flutes and two percussionists. The middle piece ‘Freehand Poitras’ is for string trio, but like the other works on the disc it is typified by the use of long sustained tones and slow glissandi. Three exquisite pieces by the Berlin-based composer who uses drawings as the basis for her compositions.
