More than a hundred free concerts make up the musical program of La Mercè 2026, which from September 23 to 27 will turn the squares and streets of Barcelona into urban stages for a great international festival, with musical projects from some thirty countries. Música Mercè, BAM, and Acció Cultura Viva are the three pillars that shelter a program in which, once again, the most popular names, mostly local, gather at the concerts on Avinguda Maria Cristina and those on Bogatell beach. On the first stage, among others, Maria Jaume, Els Catarres, Els Amics de les Arts, and the former singer of La Oreja de Van Gogh, Leire Martínez, will perform; on the Poblenou stage, among others, Al·lèrgiques al Pol·len, Buhos, Miki Núñez, Svetlana, and La Pegatina will perform, who according to Gisela Sais, curator of Mercè Música, will offer a concert with "a large part of the repertoire in Catalan". Two concerts for these stages are yet to be announced: a "surprise artist" on Avinguda de Maria Cristina and a "group to be announced" on Bogatell beach.
