When we caught the 2006 Whitney Biennial we zoned out to dark video installations featuring Japanther, stared into Buckets from Jonestown strapped to giant wooden carts and ogled at partially demolished walls surrounding giant rotating candle holders that were dripping wax. It was awesome (duh), we brought our moms (seriously), and we’ve been counting down the days til this year’s edition, which officially opened yesterday. Featuring 81 artists, the biennial actually extends beyond the museum’s walls and into the Park Avenue Armory, where F44 cover stars Gang Gang Dance will be playing on Sunday evening. New York Magazine says the whole thing has a “neo-hippie outlook”—referring to numerous collaborations and communal atmosphere—which we’re into so you’ll see us there trying to explain to mom (again) why this is important.
