File this under "Why don't I live in New York?" Earlier this week, Make Music New York put on a performance of Xenakis's percussion piece Persephassa, featuring performers situated on floating platforms & along the shore of The Lake in Central Park. The audience enjoyed the performance from row boats in the middle of the lake. The event description instructs that after the "stunning conclusion, members of the audience will row their boats back to the dock."
