Line Noise is a podcast about electronic music from Philip Sherburne and Ben Cardew. Episode eight sees us visit the Sónar Barcelona offices to talk to festival co-director Enric Palau about the past, present and future of the “advanced music festival”, including the most techno dinner ever, PXXR GVNG and the decision to book Skrillex. We also ask: has Joakim made actual Tropical House? And chew over new releases from Anohni, Harald Björk, LMYE and Clatterbox.
