What is Mamby? That is the question many puzzled dance music fans have been asking themselves for a few weeks now. Well, that mystery can finally be laid to rest, as the new Chicago-based festival has just announced it’s inaugural lineup. Scheduled for July 11th and 12th, Mamby On The Beach is taking over prime real estate on Oakwood Beach, and bringing in some of the biggest names in funky house and soulful techno. The headliners are Empire of the Sun, and Passion Pit, but my love for this lineup stems from other names on the bill, including: Art Department, a DJ set from James Murphy, Cashmere Cat, J. Phlip, Matthew Dear, Moon Boots, and No Regular Play, just to name a few. Tickets are readily available here , and right now will only set you back about $120 for a 2-day pass. Not bad at all for such a stacked lineup. See everyone out on the beach!
