Selling New York" is a realty reality show on HGTV in which teams of realtors (no, I will not capitalize that word) show and try to sell very high-end properties. It's condo porn, plain and simple, but oh so tasty.
In Episode HSNY-107H, "Extra Special Spaces," agents drum up interest in a $13 million Soho loft by inviting top brokers to a charity event in the space. The evening includes a performance by the great jazz pianist/composer Fred Hersch. He's not mentioned by name or listed in the credits but there he is at a lovely old Steinway starting at the -03:29 mark, near the end of the show.
Watch closely and you can glimpse him earlier, standing around and chatting. He plays for about ten seconds.
