Icona Pop + Born Ruffians + Free Energy + Chad Valley + Flume

CMJ. In the top slot at this Windish showcase, all hail the Bananarama-esque, straggly pop stylings of Swedish duo Icona Pop, pumping out catchy, melodic, bratty dance pop. Its summer indie hit, “I Love It,” reminds us of the Black Eyed Peas' “I Gotta Feeling,” in the best possible way. Setting the stage: suitably scrappy-sounding Canadian trio Born Ruffians and righteous classic-rock revivalists Free Energy, plus a DJ set from Penguin Prison.
