Keith Huff likes to write about blue-collar thirtysomething white dudes from Chicago. His magnum opus, A Steady Rain, made a high-profile Broadway debut back in 2009—high-profile because it starred Hugh Jackman and Daniel Craig as a pair of Windy City cops (both were good). With his latest, Garbageman, Huff is maintaining a considerably lower profile, at the 60-or-so-seat Chain Theatre space on West 36th Street, and instead of Jackman and Craig we get Deven Anderson and Kirk Gostkowski. But once again he’s given us a two-hander about hapless blue-collar dudes, trying to make sense of a series of bad fates, and in so doing, revealing both their humanity and their lack thereof.
