Ratio 3 in San Francisco recently opened a group show entitled Magnetic North featuring the work of Birgir Andrésson, Buck Ellison, Sigurdur Gudmundsson, Roni Horn, Ryan McGinley, Takeshi Murata, Geof Oppenheimer, Mitzi Pederson, and Christopher Williams. Through photography and sculpture each artist grapples with themes involving the natural world and the effects mankind has on planet earth. Multiple approaches are taken. Mitzi Pederson’s concrete and glitter fragment sculptures glisten as they speak of a broken environment while Sigurdur Gudmundsson’s Project for the Wind remains playful. The show is on view through May 11, 2013.
