A lot of bluegrass outfits adhere strictly to the traditions of the genre, at times so much so that it feels a little academic and sterile. The Dixie Bee-Liners probably won't be accused of being overly devoted to convention. Their take on bluegrass weaves in other influences and instrumentation, particularly country and some flute playing that recalls British folk acts like Fairport Convention. Lead singer Brandi Hart sings in a clear, clean tone, harmonizing beautifully with the other band members on the group's latest, "Susanville," a concept album about travelers on the interstates and blue-line highways of America. Plinking, plucking banjo and mandolin strings move the songs forward while the fiddle scrapes out beautiful melodies and buzzing drones alike. This show would probably a good bet for anyone who's into that Be Good Tanyas/Avett Brothers indie-bluegrass milieu.
