Our Critics Week series continues with a look back at year in classical music and opera. Washington Post chief classical music critic Anne Midgette joins us with her picks for the year’s best. Plus: Tis the season – for Handel’s “Messiah.”  Every year at this time, Handel’s big piece for chorus, soloists and orchestra takes over the NY concert scene. Kent Tritle, conductor of the Oratorio Society of NY and Musica Sacra, and host of the new “Choral Mix with Kent Tritle” on WQXR, updates us on all things "Messiah."
