My bet was that street performers in Barcelona have to pass some sort of licensing exam. The ones we saw were all great. One group outside the Cathedral played a sort of gypsy-tinged, new agey jazz. You can see people were digging into their pockets. They were really good.
Not far away was a brass band playing traditional Catalonian music. Maybe my video will work here. Unfortunately, it's reallllly short.
I could go on and on. On the steps of the other cathedral (what city has two?!) there was a great choir. Then behind that, a kids performance, with baby drummers, baby clarinetists, and a rapper. All in all a great city. But of course, you come here to see THIS guy!
