Punch Brothers, whose name is taken from the Mark Twain short story, Punch, Brothers, Punch!, are just plain incredible. I know folk/bluegrass isn't for everyone, but this is some of the best music and musicianship I have heard in years. Masters of highs and lows, they do an amazing job of not making this the same old bluegrass you have heard time and time again. It is neither all happy-go-lucky, nor is it all songs about suffering and loss. Rather, it is filled with nuance, passion, and holds interest with masterful song craftmanship. I can't recommend this enough.
