Vermont’s classical music lovers look forward to the Green Mountain Mahler Festival’s annual performances of Ludwig van Beethoven’s Ninth Symphony. For the 10th year, the ensemble, formed by bassist and University of Vermont Medical Center physician Daniel Weiss in 2002, breathes life into one of the German composer’s most famous works. Guest vocalists Lillian Broderick, Linda Radtke, Wayne Hobbs and Erik Kroncke join the GMMF orchestra and chorus in concerts in Stowe and Colchester. Conductor Daniel Bruce and chorus master Kroncke direct. Proceeds from the January 1 recital benefit Age Well, a nonprofit that provides services for seniors.
