Klaus Biesenbach of MoMA PS1 and Courtney Love of...well, of Courtney Love -- are hosting a Halloween
fête as PS1. The event includes a costume workshop for participating artists
(of which there are many), a costume parade, and a Halloween party with
music by weblebrity Mykki Blanco.
Expect for shit to get crazy and to see Courtney and Klaus in

do, like, say, organizing this costume contest, than to set up a
PatrickMcMullan.com account?)
