In the midst of recording their newest album, pop trio Hey Anna is set to release their single “By the Bay (La Revolucion)” and will celebrate with a performance at Mercury Lounge tonight, August 8th.  Fronted by the three eclectic Rauch-Sasseen sisters, the single follows self-titled EP “Hey Anna” and their more recent “Pompette,” both short collections of energetic pop layered with quirky synths and dissonant harmonies.  Crafting intricate vocal layers like only sisters can, the girls are bringing unabashed joy to the Brooklyn music scene, and we are loving their energy. Be sure to come party with the band tonight, and watch their video for our favorite Pompette track “Dance Until Three” here. - Jillian Dooley
