Waiting for the release date of an album sucks. Downloading a leaked version sucks more. Makes one feel icky. You know what doesn’t suck? NPR’s First Listen. Each week, the fine people at NPR music work with artists to offer these full-album streaming previews, sometimes several weeks before the release date. It’s also a great way to find new music, since you get a complete picture of an artist without a hint of moral ickyness. I first heard about tUnE-YaRdS on All Songs Considered, and since her new album w h o k i l l is coming out tomorrow, I took advantage of the First Listen preview. It’s wildly enjoyable, full of every musical style you can imagine. With one set of vocal chords, Merrill Garbus produces a dozen different voices, but the album still has the feeling of a cohesive, complete and totally listenable piece of art.
