We don't know if Chopin, Molière, Colette, Jim Morrison, Édith Piaf, Oscar Wilde, and other famous denizens of Père Lachaise were disturbed by the keening sounds of Bruce Ackley's soprano saxophone on this cold January afternoon. But a security guard took issue with our lack of a permit, and he escorted us out of Paris's celebrated sprawling cemetery. Ackley was being filmed by the Ideas in Motion team for a documentary, "Cleaning the Mirror," about jazz saxophonist John Coltrane's historic collective improvisation piece "Ascension." Ackley's group, Rova Saxophone Quartet, was in Paris performing its contemporary "Electric Ascension" version. Coltrane was in Farmingdale, NY, where he was buried (in Pinelawn Memorial Park) in 1967.
