The Seville Containers festival has published a catalog that includes its 20 years of history. I have the pleasure of appearing in it several times, even as an audience.
This festival is the longest-running in Spain and its very existence is an artistic act in itself. It is, above all, an act of resistance and passion on the part of its creator, Rubén Barroso.
