Des Moines is getting some mighty nice spillover from the massive Lollapalooza music festival in Chicago, where my 18-year-old son is no doubt having the time of his life, along with his half-sister. Two bands that are playing to thousands of people in the Windy City this weekend will play on much smaller more intimate stages in Des Moines soon after. The Black Keys play at the funky old Val Air Ballroom here on Sunday and even more surprisingly, Phoenix plays at People’s Court, a smaller venue in downtown Des Moines, on Tuesday (we’ll be there…and maybe at the Black Keys too – I’m a fan of the theme song they wrote for the new HBO show “Hung,” which also is set in my hometown of Detroit.)
