The opening concert of the 21C festival featured an all Osvaldo Golijov programme presented by Against the Grain Theatre. It was preceded by a very informative conversation between Joel Ivany and the composer. My main takeaway from that is that Golijov writes for people not instruments. If the people he has in mind for a piece play a certain combination of instruments that’s what he will write for and if circumstances demand it he will readily make changes. We saw that last night when cantor Alex Stein was unable to perform in K’vakaret (for cantor and string quartet) and Juan Gabriel Olivares stepped in on clarinet instead.
