Organ Blues just came out with a powerful new release This Didn’t Just Happen. The indie grunge three-piece have addictive songs that are reminiscent to Pavement and Modest Mouse, and already have Philadelphia Weekly dubbing them “Fishtown hetero life partners inspired by Philly Grit, who make bluesy, slightly grungy rock for space outs.” Not bad for just a few short months! Although on a different side of the spectrum, the progressive electronica stylings of Mirador have also gained some attention from us lately. The three demos from an upcoming EP collection tentatively titled Chapel all have a worldly and ethereal sound that feel like a walk through a mystical temple. When both bands play tonight’s show at North Star Bar, it should be an interesting ride. North Star Bar, 2639 Poplar St., 9pm, $8, 21+ myspace.com/organblues, myspace.com/echomenopolis – Bill McThrill
