From the Youtube Page: On the 130th anniversary of the founding of Banco Sabadell we wanted to pay homage to our city by means of the campaign “Som Sabadell” (We are Sabadell) . This is the flashmob that we arranged as a final culmination with the participation of 100 people from the Vallès Symphony Orchestra, the Lieder, Amics de l’Òpera and Coral Belles Arts choirs. https://www.bancsabadell.com
