Henry Rollins is a D.C.-native punk rocker, a spoken word artist, a frequent TV show host, and, last but not least, a vigorous LGBT ally. But wait, there's more. He's also a photographer -- and an adventure photographer at that. Rollins will appear next week as part of National Geographic's "Music on … Photography Series," discussing some of his full-color images taken in some of the world's toughest, most depressing corners and published in the new book Occupants. Tonight, Friday, Oct. 7, at 7:30 p.m. National Geographic Society's Gilbert H. Grosvenor Auditorium, 1600 M St. NW. Tickets are $40. Call 202-857-7700 or visit nglive.org.
