Punch Brothers - "Punch" (2008)
Everyone's heard Nickel Creek's sentimental cover of Outkast's "Hey Ya." No one's ever heard their semi-off kilter bluegrass band, Punch Brothers. Concept alternative-bluegrass album concerning a divorce (The Blind Leaving the Blind in 4 Movements), with elements of the Schoenbergian school of 12-tone serialism. Not your standard Americana release. Recommended.
PS) I looked everywhere for this. I'd appreciate some appreciation :P.
Edit: "The Blind Leaving The Blind" is considered a "classical bluegrass" composition, written for a quintet, debuted in Carnegie Hall. Serious business.
