We’ve been big fans of Aussie Courtney Barnett since January 2014, but the world’s caught on and she’s been taking it by storm in concert in support of her new album Sometimes I Sit and Think, And Sometimes I Just Sit.  She received raves at last weekend’s Bonnaroo, and showed up last night on Fallon’s Tonight Show (her second performance for Fallon following last year’s) lto perform the punked-up Pedestrian At Best.  We will admit it’s not our favorite song of hers (that would be Depreston or Avant Gardener), but there’s no denying Barnett performed the song with passion and a vengeance.  Check it out below.
