"We’re looking at 40 plus acts to perform during that weekend, with 10 on the main stage," Rossi said at a Tuesday afternoon press conference. Other national acts confirmed so far include Yonder Mountain String Band , Girl Talk , and Drive-By Truckers . Organizers are hoping to attract 15,000 fans on the holiday weekend.

Rossi says Des Moines city leaders are hoping 80/35 will become a "signature event" over the Fourth of July holiday. "And it was a nice hole in the schedule…we’re actually picking up a lot of bands that are routing to other festivals in the same time frame. So, it’s working out quite well," Rossi said. The non-profit DMMC secured $400,000 to produce the 80/35 Music Festival.

Rossi admits his organization has already spent a "good share of that," but believes there’s enough money to continue booking more national, regional and local bands. Tickets for 80/35 go on sale Friday, online at www.IowaTix.com .
