Yesterday we passed this sign, right across from Northern Territory near the Williamsburg-Greenpoint border, and wondered what it was all about. Is this squat building on the corner of Meserole and Franklin the home of FOMO Anonymous? Nope — turns out it’s a stealth marketing campaign aimed at building even more buzz for Aussie songstress Courtney Barnett, aka the Sheryl Crow it’s okay to like. Her people let the cat out of the bag today, with this video of Barnett doing an unannounced live show a couple of days ago on the streets of London.

Of course, Barnett fans would’ve recognized “Nobody Really Cares If You Don’t Go To The Party” as the title of a song (her new single) off her debut album Sometimes I Sit And Think, And Sometimes I Just Sit. It’s also consolation for those who didn’t get into her one-night-only art show. She’ll play Madison Square Garden, opening for Blur, on Oct. 23. Keep in mind, nobody really cares if you go to the concert.
