Josep M. Folch i Torres' Pastorets (Shepherds) is performed each year at the Centre Cívic Vallvidrera - Vázquez Montalban, but with extra characters and scenes in their version: Els Pastorets de Vallvidrera. Counting actors, musicians, singers, directors and technical staff, it involves over three hundred people. It is a modern, family production with a present-day slant, part of an ongoing renovation of the traditional nativity play.

The amateur theatre group that performs the play every year is one of the groups supported by the Centre Cívic Vallvidrera - Vázquez Montalban, which is in the Sarrià-Sant Gervasi district. This municipal centre, which was opened in July 2002, brings together a large part of the neighbourhood's cultural and association initiatives. It has a programme of youth and cultural activities and workshops, and various organisations working in these areas, such as the Can Pujades consumer cooperative, the Mont d'Orsà residents' association and the Coral Collserola choir are based there.
