Does creativity follow an arc with age?  Is a period of peak creativity followed by inevitable decline or is there, perhaps, a qualitatively different, kind of creativity in the later years of life?  Linda and Michael Hutcheon; literary scholar and physician, explored this in their book Four Last Songs, which looked at the later works of Verdi, Strauss, Messiaen, and Britten.  Last night they appeared in the Confluence Concerts Salon series to provide further thoughts with reference to the works of Messiaen and Leonard Cohen.  Their thoughts were interwoven with performances of works by Messiaen and Cohen performed by Robert Kortgaard, Patricia O’Callaghan and Larry Beckwith.  There’s no need to read my description of the show.  It’s freely available on Youtube.
