Those interested in participating in the Rockin' Sierra Concert, an initiative by the Culture department of the Collado Villalba City Council, still have time to register. This unique musical event aims to bring together amateur and professional musicians, as well as municipal and private music schools from the sierra.

The concert is scheduled for May 22, at 9:30 PM, at the Carpa de La Malvaloca. Participants will collectively perform five classic rock songs in both English and Spanish, and will also have the chance to play two songs with guest artist Jorge Guillén, known as Strad.

The registration period will close on May 15 or once the participant quota is filled. The initiative by the Collado Villalba City Council, through its Culture Department, seeks to form the largest rock band in the region, uniting drummers, bassists, guitarists, keyboardists, and vocalists from the Sierra.
