Stages across Spain will fall silent on Wednesday (20May15) as musicians protest the 21 per cent increase, according to Billboard.com.

A statement from singer Garcia reads: "It's a brutal injustice. The political injustices against the world of culture is placing many of our colleagues in critical situations.

"Not only artists but all the people from different disciplines who try to make a living honestly in this industry, from truck drivers and chauffeurs, light and sound technicians to caterers."

Concert promoter Neo Sala of Doctor Music adds, "There are international artists who don't include Spain on their tours or only go to one city. It's not worth it for them to come."
