REO Speedwagon [ tickets ] will headline the "Ridin' the Storm Out-Floods of 2008 Relief Concert" July 16 at Prairie Meadows in Polk County, IA.

In a statement, REO vocalist Kevin Cronin said, "I feel a deep loyalty and a responsibility to do whatever we can to help our Midwestern brothers and sisters in their time of extreme need. We can't be there filling sandbags, but we can rock. Hopefully, with this concert we can raise money, as well as morale, for those in need."

One-hundred percent of proceeds from the concert, which also will feature the Little River Band, will go to flood victims. Additional performers are expected soon to be announced for the 21-and-over show.
