The New York Philharmonic, one of America’s greatest orchestras, still did not have a concert hall worthy of its status. Indeed, on the site of Lincoln Center, the current David Geffen Hall (formerly called Philharmonic Hall and then Avery Fisher Hall) was inaugurated in 1962 with acoustics that have never convinced music lovers. This October, back in the completely refurbished venue with new spaces, they will be able to test the work of Paul Scarbrough of Akustiks who reduced the number of seats by 500 to move the stage forward to improve the acoustics.
