Sónar is a pioneering festival of music, creativity, and technology, held annually in Barcelona since 1994. Split between two venues — Sónar by Day at Fira Montjuïc and Sónar by Night at Fira Gran Via — the festival bridges cutting-edge electronic music with digital art, audiovisual performances, and tech conferences. Sónar's lineup ranges from experimental electronica and techno to hip-hop and avant-garde sound art. The festival's Sónar+D program brings together startups, researchers, and artists exploring AI, VR, and the future of creativity.
