Artist: Pete YornMP3: “Precious Stone,” from Yorn’s self-titled album, due Sept. 28Rating (Skip, Stream, Buy): StreamDownload: For free at PeteYorn.com if you RT it.Pete Yorn’s “Precious Stone” is full of big, open, New Jersey chords, complete with Yorn’s signature mournful reverb at the top. It’s nearly raucous, held back by the fact that Yorn’s never sounded this self-conscious. The guitars on this first single from Yorn’s self-titled, Frank Black-produced record are begging him to let loose, but he doesn’t. His voice is restrained and frustrated, even timid. It’s as if he doesn’t want the world to know that he’s trying to lay it all out on the line. But that’s exactly what he needs to do.On his promising 2001 debut, Musicforthemorningafter, Yorn sounded like a nonchalant kid (“Black”) with nothing to lose (“For Nancy”). And he was. But on “Precious Stone” he sounds like a guy feeling the pressure to break out or get out.
