Rogue Fest is mostly composed of progressive rock bands, though I think there's sometimes those that are more on the metal side. Its in Atlanta, so just making some aware if they need something to do next weekend. Takes place July 7th & 8th. Not sure if I'll make it to there or not, perhaps Friday. We'll see.
