It was hot at Markham Theatre on Wednesday night, when violinist Sarah Chang and pianist Andrew von Oeyen fed a full house of hungry audience with something temperamental, something serene, and something romantic…. Along with von Oeyen’s vibrant and solid playing, the pair produced urgency and drama through the stormy passages….Chang and von Oeyen were a musical union through hushed moments, sweet canons, or sparkling climaxes…Chang delivered her signature big, luscious sound, and it was matched perfectly by von Oeyen’s deep and full-range tone on the piano…this partnership is worth listening to no matter the music.
