Toronto-based composer Linda Catlin Smith has been well represented in Another Timbre’s ten-volume release of contemporary Canadian composers, including the eight varied pieces of The Wanderer and the two-CD set, The Drifter. Here she shares a disc with that work of concentration-camp genius, Messiaen’s, Quatuor pour la fin du temps. They’re performed by the English ensemble Apartment House, and share the instrumentation of violin, cello, clarinet and piano.
