On Friday and then again on Saturday evening, I drove south to the Sarasota Contemporary Dance studio for the first installment of what turned out to be a fantastic collaboration. My friend and world-class cellist Natalie Helm came up with the idea: Bach Immersion Concerts, a one-of-a-kind exploration of Johann Sebastian Bach's Six Suites for Solo Cello. The idea is to present "a multi-sensory interactive live performance," and that's exactly what happened.
