The piano zaps me faster than a microwave. It makes my heart melt instantly. Sunday night was one of those blissful New York spring evenings on the rooftop at Gavin Brown Enterprise. Hosted by the lovely Evas Arche und der Feminist, it was a light crowd, cheap drinks and elegant minimalist sculptures by Peter Kortmann. There were candles above a piano and Jay Israelson performed two melodic, hypnotic numbers. Everyone hushed, listening attentively. Even the lone baby in the crowd seemed to hold its breath. Just two songs, then the crowd began to stir; the chatter resumed, the baby cooed, and I got another glass of wine.
