We're barely into the day and Grant Park's already a ganja-smoker's paradise. No surprise there. Still, that pervasive, skunky scent proved to be a perfect backdrop to Austin's Black Angels, whose flickering tremolo-laden guitars easily cut through the second-hand smoke to set up singer Alex Maas. The frontman's haunting moan makes him a ringer for Jim Morrison, though the Angels' deep, dark kaleidoscopic grooves call to mind something far more menacing than the Doors even at their bleakest. Playing largely from their most recent album, 2010's excellent Phosphene Dream, the Texans cast a twisted, psychedelic silhouette against the swirling red and yellow lights spilling light down from the stage rafters. It's tough to see those flickering effects in the bright of day, but the band's hypnotic sound was a soothing contrast to the blazing sun. As the fuzz-guitar froth simmered to a boil, I couldn't help but think how foreboding it all was given the time of day (a similar vibe to when Disappears opened on the same stage, Bud Light, last year). That's hardly a complaint. Kudos to the Black Angels for rising to meet one of Lollapalooza's biggest challenges: maintaining your cool when out of your comfort zone.
