Michael Tilson Thomas and the San Francisco Symphony add their extraordinary September 2019 recording of Igor Stravinsky’s Symphony of the Psalms [1948 revision] to the San Francisco Symphony’s 2019–20 Digital Concert Series. This breathtaking piece—where we hear Stravinsky returning in the most fantastic way to the idea of a symphony as a mingling of sounds—is further enriched by the vocals of the SF Symphony Chorus.
