In a Spanish plaza, a young girl drops a coin in front a tuxedoed Bass player. Pretty soon, the lone performer has been joined by a full orchestra. Staged as part of the 130th anniversary of Banco Sabadell, the flash mob is only part of the what makes this video work so well. The production is almost too clean, as if it were staged. But who cares – free, quality public art is its own best justification. This video is an old one, but still a good one.
