River's Edge Music Festival
Date: June 23-24, Harriet Island, Saint Paul, Minn.
Corporate backer: Citi (C)
Sure, Citi's coffers help bring in big acts such as The Dave Matthews Band, Tool and The Flaming Lips and 26 other bands and keep ticket prices down to $110 for a two-day pass (though VIP packages go for two to five times that). But that sponsorship also gives Citi a chance to showcase its Citi Private Pass, which gives Citi cardholders access to ticket presales and preferred seating. Consider everyone's back scratched.
