these guys are spectacular. putting them up against a headliner would murder me though cuz it'd probably be muse and my gf reeeeally wants to see muse. I wonder how many people missed out on gogol cuz of bjork? this could be similar
You could split up and see different acts if there are conflicts like that. My guy and I do that every year and it works out pretty well. Sometimes it's the only way to ensure that you both are truly happy with your festival experience.
