WCBS-FM’s jangly oldies rotation sealed my Byrds fandom at an early age. So maybe I’m biased, but co-founder Roger McGuinn’s Folk Den blog is really something special. McGuinn eschews predictable tour journals and studio diaries here, instead shining a light on some great old folk obscurities of the “Anthology of American Folk Music” variety (titles like “Frozen Logger” and “Old Chisolm Trail” give you an idea). Each post includes an original recording of the song, along with lyrics, guitar/banjo chord progressions (even some old-time scores), and fascinating commentary from someone who clearly lives and breathes the genre.
