Given that Doug Martsch is blessed with one of the most distinctive voices in rock, it´s not surprising to find the Built to Spill frontman in a familiar place on his solo debut. But this is more than just an acoustic spin on his Boise, Idaho, band´s off-kilter psychedelic noise. Now You Know is sweet and jangly, a homespun blues record made in the late hours of the night on battered guitars, in the same loose and grainy tradition as Beck´s One Foot in the Grave and Paul Westerberg´s Stereo. It´s endearingly rustic--from the jagged and jaunty "Gone" to the winding Neil Young tribute "Impossible"--and yet another reason to count Martsch as one of middle America´s most valuable natural resources.
