She may be most well-known as one half of CocoRosie, but Bianca Casady (aka RedBoneSlim) is also a freakishly good fine artist. This Saturday marks the opening of her exhibit at Deitch Projects in NYC. The title, Lil Girl Slim “Cosmic Willingness” Pipe Dreamz A Revelation, should be enough to draw a crowd, but the opening, which kicks off at 6 p.m., will also feature a performance by–you guessed it–CocoRosie. Brookyn’s own Bunny Rabbit says she’ll be serving cupcakes. Check out Bianca’s Lisa-Frank-on-acid art and eat some sweets.
