The Co-Prosperity Sphere, an experimental cultural center in the Bridgeport neighborhood of Chicago, will be hosting the Matchitehew Assembly, a music festival of sorts, on June 5th and 6th. The festival will be a two day, all-ages assembly of musicians from across the nation and otherwise, with styles ranging from traditional black metal to noise; a collection of extreme elements that encompass the spectrum of dark sound, which sounds a little LOTR to me, but could also mean a very good time. The assembly is not accepting sponsorship or promotion from any corporate company; groundwork for the assembly is volunteer-based, and the host location is non-profit. You should definitely pre-order tickets online here, and check out the really intense line up here.
The Co-Prosperity Sphere is located at 3219 S. Morgan in Chicago, Illinois.
