A sharp-eyed and detail-oriented DRA super-fan recently posted this picture on one of the Ryan Adams Facebook fan pages, a shot of a scene in a season-two episode of the supernaturally themed dramatic series “Buffy the Vampire Slayer.” Note the poster in the background — for Whiskeytown’s alternative-country signpost Strangers Almanac, an album that happened to be released the same year that the “Buffy” series debuted (1997). I’d say that somebody on the show’s crew was a fan.
