Elena Siyanko, Executive Director of PS21, in her introductory comments preceding Alarm Will Sound's performance of John Luther Adams' Ten Thousand Birds, said that this event has been in the works for a year. Its purpose, conceived months before there was any hint in people's minds that the performance would occur under the restrictions imposed by the pandemic which continues without an end in sight, at least in the United States. The particular features of the new performance structure and the determination and resourcefulness of Ms. Siyanko and her staff have made PS21 a pioneer in offering live performances under safe conditions. The performance of Ten Thousand Birds was intended to showcase the new PS21 and its new semi-open performance space to the public. The beautiful grounds surrounding it are in integral part of its design and function in a way quite different from Tanglewood and SPAC, where lawns simply provide expanded seating for those who prefer to be out in the open.
