Courtney Barnett's songs are wild, shaggy and wordy, mixing witty, mundane, and sometimes heartbreaking observations with devastating self-assessment. And with a sound rooted in the slack jangle-rock of the late 1980s and the early 1990s, Barnett delivers plainspoken lyrics and roll off the tongue as if she's thinking them up on the spot. You can hear that in her break-out song "Avant Gardener" or in "Pedestrian At Best," from 2015's superb album, Sometimes I Sit and Think, And Sometimes I Just Sit, in which she spits off a list of personal insecurities and internal monologues to an former love. The Australia native plays songs from Sometimes I Sit and Think, And Sometimes I Just Sit in a 2015 session, recorded live in The Greene Space.
