Take what happens to Icona Pop in this week's installment of I AM ICON, for example. The girls are headlining Mexico City's Electric Planet festival, and nothing goes smoothly. The sound system is subpar, the DJ's foot goes through the floor, not to mention there's a massive language barrier between Icona's team and the festival organizers. No matter. The sign of a true performer is their ability to leave the drama backstage and deliver the best show possible, because, at the end of the day, it's about the fans. And, the enthusiasm of the concertgoers in Mexico City puts the rest of the world to shame.
