New York jazz pianist, composer and Columbia and Julliard grad Ben Rosenblum is known for his rhythm block-chorded, Bill Evans-esque chops. With bassist Kanoa Mendenhall and drummer Ben Zweig he has formed — what else — the Ben Rosenblum Trio, which will present its modern jazz sounds to the lucky people at the Sanctuary tonight at 7:30 p.m. ($10-$20 sliding scale). Ben will be playing the in-house Sanctuary piano, a 1914 Steinway Upright made in Astoria, Queens, in the factory on the titular street/place. When I lived in NYC, I used to find myself wondering: Were there more garrotings around that piano district in its heyday? Perhaps The Power Broker author Robert Caro owes us a book about it.
