Another group show based on the to-and-fro between artists and music and musicians and art, "White Noise" boasted a solid cross section of youngish musicians (Jason Ajemian, Brendan Fowler, Mario Diaz de Leon), visual artists from older generations with a verifiable interest in rock music (Robert Smithson, Raymond Pettibon), and figures who work extensively in both media (Yoko Ono, Christian Marclay, Jutta Kocther, Rodney Graham, Emily Sundblad).
