Robyn Gets Chicago Dancing at Pitchfork Music Festival

The first night of the 2010 Pitchfork Music Fest commenced with sweltering temperatures reaching the mid 90s, but it didn't deter a crowd of of thousands there to watch Swedish pop singer Robyn give a highly energetic set in Chicago's Union Park.

Wearing a revealing dress with the sides and back cut out, lacy tights and sunglasses, the blonde bombshell aimed to bring her icy coolness to dampen the heat. She opened with two songs from her latest electro-pop record 'Body Talk Pt.1,' including vocoder-infused 'Fembot' and 'Cry When You Get Older.'

Upon hearing her catchy, electo beats, the crowd immediately began jumping up and down and danced along with Robyn, who strutted her stuff. The dancing probably only aided to the heat, but no one seemed to mind. "It's so damn hot, Chicago!" Robyn screamed to the crowd. "How you doing people? We got on a flight from Sweden to come here."

Robyn took off her sunglasses and continued to cavort and gyrate on 'Cobrastyle,' her boisterous cover of fellow Swedes the Teddybears' song, which appeared on her self-titled album 'Robyn.' The crowd sang along to another new one, the huge single 'Dancing On My Own,' where she wrapped her arms around herself and danced alone. Things slowed down for the pulsating break-up anthem 'With Every Heartbeat,' but the momentum picked up again for 'Dancehall Queen.' Penultimate song 'Don't F---ing Tell Me What to Do' began with a pre-recorded litany of things that are killing Robyn, like drinking, and the scintillating dance music coerced her to playfully hit the hi-hat and jab the air with punches.

She ended her 10-song set with an amplified version of 'Be Mine,' featuring synths that washed over the rest of the melody. "Thanks for standing in the heat," Robyn told the drenched the crowd as the dance party wrapped.
