Really fascinating historic telecast performance of Mahler 2 by the New York Phil under Bernstein. Originally broadcast a few days after President Kennedy's assassination in 1963, and performed in tribute to the former President.

According to the description and the post on Facebook, will only be available for the next 24 hours (as of about 5PM PST)
