Hamburg, Germany's Christopher Rau and Moomin will perform a live set as Roaming; you may have heard the duo's new EP (out on Smallville), which has been on heavy rotation. Kicking things off are PTA (known to the acronym-adverse ad Pittsburgh Track Authority), Pixelife and Discovery residents Free Magic and Faso. The promoters tell us to expect a fantastic quadraphonic sound system. We like the sound of that. Go to adiscoparty.com for more info.
