Overview
Sónar Barcelona runs on a defined split between Fira Montjuïc and Fira Gran Via, with Barcelona city center acting as the practical base for most attendees. The shape of the trip is not just a stack of concerts: afternoons lean into Sónar by Day and Sónar+D, then the energy shifts toward late hours, transfers, and bigger crowd pressure at night, with some people adding OFFSónar or other official supporting venues in Barcelona around the edges.
