Local composer Tracy Spring is debuting at least part of a new choral arrangement of Your Heart Is a Muscle the Size of a Fist at the Co-op sponsored Martin Luther King Day celebration at BUF on Monday, January 21st starting at 7pm. Email her at firstname.lastname@example.org if you want to give the SATB sheet music a try! She will send you a .pdf of the latest version. There are also sectional mixes of audio files available for those who prefer to learn by rote.
There will be a run-through of the piece somewhere in the building on the day of, at 6:15 pm, hopefully in the Sanctuary with Karen FitzGerald on piano (who is performing with Tracy), but if that space is not available for the run-through, probably downstairs.
