Chiodos' will be heading out on tour this fall with Atreyu, [url=http://www.absolutepunk.net/blessthefall]Blessthefall[/url], and more. You can check out the dates here.
Good move to get Blessthefall, not so much Atreyu.
Edit: But Architects and Endless Hallway are both pluses in my book. Sad that they are playing the Chicago House of Blues five days after Attack Attack! headlines it. :/
