New York's Punch Brothers are a niche interest that is rapidly growing; their blend of Americana and bluegrass, stretched across jazz time signatures and spliced with elements of funk and rock, won them Grammy nominations in 2010. This is no barrier to boredom though, and the band's twinkle-toed banjo runs and acoustic duelling fall flat here, hobbled by dreary songwriting. "This Girl" and "Hundred Dollars" are cases in point, lumpen drivetime fare with only a hint of bluegrass zip. And though a cover of Radiohead's "Kid A" taps into the original's weirdness, little else surprises.
