With members of French, American, Swiss and Vietnamese parentage, based in several cities around the globe, they're a ramshackle olde worlde acoustic outfit with a theatrical bent and a tendency to dress like 1930s Prohibition outlaws who make a mess of sound that takes in folk, country, blues, jazz and cabaret. Their first UK release – they've already established a huge following in France, where their debut album, Gee Whiz But This is a Lonesome Town, sold 70,000 copies and was certified Gold – is a single called Jimmy and it sounds like it was recorded around the turn of the last century, all jaunty bluegrass guitar, wistful harmonica and lyrics about roaming buffalo.
