This is typical Catalan advertising. This is an advert by the Sabadell bank for their 130th anniversary and my own view is that it is contrived. On a more somber note this bank is a bit stuffed having loads of toxic loans.
Hollis, that was beautiful. Thanks for posting a gentle reminder that friends and strangers alike can come together and create beauty and harmony while the spectators take a moment out of their day to appreciate it, and hopefully remember to carry it forward.
