The jazz offerings in the city this month offer the opportunity to explore the music from a number of different perspectives. For a historical one, the ICA is hosting The Freedom Principle: Experiments in Art and Music, 1965 to Now through next March. The exhibition, which opened last year at the MCA in Chicago, tells the story of the influential Association for the Advancement of Creative Musicians (AACM) and its intersections with the visual art and culture of the era. It’s a must-see, and also features a number of performances to coincide with the show. But aside from that, this month’s standout concerts provide a number of different angles.
