We thought the double header gigs in Atlanta were going to be the Halloween shows this year but it looks like we called that too early.

Today STS9 has announced that they will be playing in Philadelphia, PA on October 31st, 2012.

Sound Tribe will be bringing their Great Cycle Spectacles show to the City of Brotherly Love for the first time since 10/21/2011 when they played the Electric Factory to a sellout crowd.
