With Global Welcome Ambassador Taylor Swift high above, looking down on us from one of two Tribeca lofts, it’s easy to lose faith in the New York music scene, or any residual edginess lingering therein. But the Brooklyn Rock Lottery is here to prove, once again, that this city is still home to the real deal, creatively speaking. Today, members of 25 hand-picked bands including the Yeah Yeah Yeahs, Au Revoir Simone, Crocodiles, Parquet Courts, and St. Lucia will take the challenge. They’ll be divvied up, via a random lottery, into five groups, given 12 hours to write and rehearse five new songs (limited to one cover), and will perform their handiwork for you, the live audience, later tonight. Come hear your local acts test their chops after a hard day’s work — all proceeds go toward the Harmony Program, which provides after-school music education to NYC’s underserved communities.
