See that one little dark purple spot. That's the one remaining orchestra ticket to Koyaanisqatsi tonight. ACT NOW and you could be that little purple spot! As I see from the NY Philharmonic's website, there is one available seat in the orchestra, and in all, there may be only about 10 tickets left available all together for both shows.
If you are left out in the cold, you can console yourself with the magical production of Satyagraha across the way at the Metropolitan Opera which opens Friday. Visit metopera.org. For a special offer, buy one ticket and get your second at 50% off, use the code SATYA09.
