Houston-based, soul-meets-funk psychedelic, “world music”-inspired rockers Khruangbin are preparing to play their fourth sold out Philadelphia show this year, when they headline Union Transfer this Friday, November 30th.   The trio first sold out neighboring Eraserhood venue Underground Arts this April (The smallest show I’m guessing they’ll ever play in the City of Brotherly Love and Sisterly Affection.), before opening two sold-out shows for Leon Bridges at the massive; 2,500-capacity; Fillmore earlier this Fall.  The band continue to tour behind their sophomore effort, Con Todo El Mundo, which dropped this January, courtesy of Dead Oceans, which received profound praise from the likes of Pitchfork, NME, and Clash.  And although the band seem to remain largely ambiguous, refusing to define their sound (which is nearly as hard to pin down as figuring out if any given Morrissey show will actually happen) and only carrying out a rare interview, it is clear that they are quite massively loved by their fans (Who are also next to impossible to decipher.  Their UA crowd looked – and acted – like an incomprehensibly bizarre blend of Melvins and Dave Matthews fans.) and will be selling out mega-venues for quite some time.  If you’re lucky enough to already have a ticket, make sure to get there early for Ginger Root, who describes themselves as, “Aggressive Elevator Soul Powered by Chick-Fil-A Sauce,” and takes the stage at 9.  In the meantime, listen to Khruangbin’s recently released, seasonal single, “Christmas Time Is Here,” a rare opportunity to hear the nearly-instrumental group sing a big.
