A city plaza is filled — slowly, and with an orchestra built from the ground up — with music (Beethoven's beloved "Ode to Joy") in this short produced for the 130th anniversary of Spanish banking giant Banco Sabadell earlier this year. The carefully choreographed "flash mob" at Sabadell, Spain's Plaça de Sant Roc includes performers from the Vallès Symphony Orchestra, the Cor Lieder Camera, Amics de l'Opera de Sabadell, and Coral Belles Arts.
