This 2026, Sopa de Cabra celebrates four decades of trajectory with a commemorative tour and the premiere of the documentary Tornar enrere, directed by Jordi Call. The piece, broadcast this Tuesday on 3Cat's Sense ficció, highlights various aspects of the band's 40 years that had often been overlooked. For instance, the group members openly admit that they do not maintain a friendship outside the musical project. In fact, the documentary begins with an argument after a concert.
