They might not hail from the States -- in fact Spinner was the band's first stop when they landed stateside -- but these London lads (Mumford & Sons) produce a sound that's every bit as Americana as our other folk-rock favorites, the Avett Brothers. That authenticity is reinforced by the band's collection of highly memorable tunes, excerpts of which we've found ourselves humming weeks after that first hearing of their full length offering, 'Sigh No More.'
