The Paper Box, a fully integrated arts complex that opened this year (and built basically to house anything and everything), is hosting the great nonprofit Arts for Progress for their Mixed Greens party, a new monthly multimedia event that features emerging artists across a wide spectrum of artistic expression. There’ll be musicians, visual and performance artists, and even a DJ or two, as well as a video installation. Attending is a great way to support two really awesome organizations, see and experience really cool things in a really cool place, and an endless cache of “I saw this [fill in the artist’s name} back when…” hipster cred just waiting to be claimed. The party lasts all night and will only set you back $8. Can a chiller, cheaper Saturday be found?
