The New York that made the Chelsea Hotel a bohemian mecca vanished a long time ago—frankly, if the best music to come out of it lately is the Libertines and Ryan Adams, bring on the wrecking ball. But it’s hard to argue that Ed Hamilton isn’t doing the world a service by serving as the storied joint’s self-appointed historian. In his book Legends of the Chelsea Hotel, Hamilton profiles and collects stories about Chelsea residents past and present like Arthur Miller, Michael Alig, and you-know-who; on his blog, Hamilton mostly bemoans every move made by the Chelsea’s new management team, from the hold music (“a bad recording of the Velvet Underground”) to the policy against unsupervised children in the lobby (“It’s a shame because the Chelsea Hotel in the old days was welcoming to all age ranges”). In other words, he’s exactly the kind of pain-in-the-ass old-timer who’ll never vanish from New York. Hamilton discusses and signs copies of his work at 7 p.m. at Olsson’s Books & Records, 1307 19th St. NW. Free. (202) 785-1133.
