The Grateful Dead spent most of their 30-year career truckin' around the world. But they always considered New York City a second home. Gary Lambert, editor of the Grateful Dead Almanac, discusses the band’s Big Apple adventures, including its free concerts in Thompkins Square and Central Park, with Patti Smith's lead guitarist Lenny Kaye, Pete Fornatale (author of The Rock Music Source Book) and Carol Brightman (of Sweet Chaos: The Grateful Dead's American Adventure). The event is tied to the exhibition "Grateful Dead: Now Playing at the New-York Historical Society." .
