At Sonar there are countless label showcases happening in greater Barcelona. Those who wanted to escape from an aseptic mass rave festival taking place in cold exhibition halls, found their gem when visitting CL records’ showcase at Teatro Principal. The old theatre is directly located at universally known Ramblas. When entering the Principal local hero Oscar Mulero already let uncompromising techno rhythms talk while Mr. Liebing still worked on his technical setup. Both artists delivered flawless sets.
