Point Counterpoint II was designed by the great architect Louis Kahn – with a unique structure that opens like a clamshell to provide a stage and acoustical canopy – for the American Wind Symphony Orchestra to use for concert tours along the nation’s waterways. After many years of attempts to sell the vessel, the owners are planning to send it to a scrap- and shipyard in Louisiana at the end of this month. Following an emotional plea from Yo-Yo Ma in The New York Review of Books, there is interest in saving Point Counterpoint II, writes John von Rhein – but donors need to be found for the purchase.
