August 11. More hot jazz happens farther north with the Hudson Opera House's seventh annual Hudson Jazz Workshop Concert. The afternoon public performance finds workshop participants joined by pianist Armen Donelian and saxophonist Marc Mommaas and none other than National Endowment for the Arts Jazz Master vocalist Sheila Jordan. Praised by leading jazz scribe Scott Yanow as "one of the most consistently creative of all jazz singers," Jordan was originally inspired by seeing Charlie Parker in the late 1940s and rose to prominence while working with Herbie Nicholls and George Russell in the early 1960s. A songwriter as well, the 84-year-old singer shines in both the bebop and free jazz idioms. 3:30pm. (Preconcert talk at 3pm.) $10. Hudson.
