"We've never marketed ourselves as confident as when we were terrible musicians," reveals drummer Axel Pi. "Before our debut gig at the Sidecar, a historic club in Barcelona, we handed out flyers and walked around the Raval district proclaiming, ‘You can't miss this concert, we're the best in Barcelona’. Although I shudder to think what we sounded like at the time, the concert was a huge success. Despite being the worst band in the world, our unshakable belief in ourselves was enough to convince the audience”.

"El Peor Grupo del Mundo" is the honest title of Sidonie's eighth album. An album that brings together ten songs full of nostalgic feeling. It's a pop record that talks about pop, the pop within pop. It's their way of expressing their love to all the groups they adore, a "we love you" in the form of a record. It is also a reminder of who they are and have always been - fans.
