The Strokes - Live at Landmark Music Festival

And as with other hugely successful rock bands, it was the lead singer who was in charge of pumping up the crowd, with Julian Casablancas yelling things like "D.C., let's rock!" and "What's up, D.C.?!" The crowd went wild, but to Casablancas, it was clearly a joke. He was playing a role and said as much outright at the beginning of the show, but that didn't stop the crowd, hungry for more entertainment, from taking him seriously.
