Finding our selves in Barcelona on the day of a general strike unable to use public transpiration to get around the city we struck out from our hotel and walked. As we neared the city center we heard the drums and the music bouncing off the walls. We were curious and decided to investigate. These guys were wailing on the street. The excitement and the groove was great. When I realized they were choreographing their moves, that made it all the better. Before we knew it, we'd been standing there watching for 45 minutes.
