On first glance, the crowd seems fairly homogenous. Yes, the majority are wearing maroon and blue stripes, while one noisy corner tucked into the top of Camp Nou is decked out in white. But the voices sound similar, the faces nearly blend together. At first it’s difficult to believe the spectators are divided by 125 years of history, their political legacies positioning them at opposite ends of a spectrum. It is only when you focus that you notice the flags being waved don’t bear the Spanish shield; that the rippling chants have a dissonance that sends them off-key before finding your ear.
