El Pais and La Vanguardia have daily listings for art openings and concerts (including many free ones), under their Agenda headings. Keeping an eye on these listings can guide you to some of Barcelona's best events, often with tapas and cava included. Performances of Castellers, the human pyramid squads unique to Catalonia, are announced in the weekend agenda section. La Guia del Ocio comes out every Thursday and lists the top musical and cultural events for the week; many hotels hand out this guide gratis.
