The trademark tenor of Russell Hitchcock's soaring voice and Graham Russell's simple yet majestic songs created a unique sound that would forever be known as Air Supply, and on August 1, the band's co-founders will bring their "50th-Anniversary Celebration Tour" to Bettendorf's Quad-Cities Waterfront Convention Center, their collection of iconic, adored hits including such pop staples as "All Out of Love," "Making Love Out of Nothing at All," and "Every Woman in the World."

On August 2, this year's Mississippi Valley Fair will offer a two-fer of alternative rock and post-grunge with its fifth grandstand concert of the summer: a co-headlining event featuring Lit, whose top-10 Billboard hits include "Miserable," "Lipstick & Bruises," and the chart-topping "My Own Worst Enemy," and Pop Evil, their own Billboard smashes including the number-one singles "Trenches," "Torn to Pieces," and "Deal with the Devil."
