According to Spin News:
Taken from her long-awaited debut album, Broke With Expensive Taste, Azealia Banks’“Wallace” was always one of the project’s standouts. It’s got this fascinating back-and-forth clang, lyrics that twirl and contort themselves up into the air like the seeds from a dandelion, and now, an equally immersive music video. Directed by Nick Ace and Rob Soucy, the interactive visuals depict the Harlem rapper staring straight ahead at you, eyes locked – until you move your own face, that is. That’s right: Ms. Banks’ video commandeers your webcam to track all facial movements. Check the “Wallace” video out here if you have Google Chrome.
