Twenty years ago Blai Casals and Manu Sabaté met at the summer camp for Young Folk Performers of the Pyrenees in Arsèguel (Lleida, Catalonia) and on the last day they asked themselves "do you want to make a group with me?". The two, twenty years later, have decided to take advantage of this event to do some retrospective of what these years have given: first alone, then with La Mata Negra (accompanied by a rhythmic base of bass, electric guitar and drums), later alone, but with Blai incorporating the bass drum and chatter (like the old accordionists of the Pyrenees) and, finally, Morena the Tradipatxanga trio with Hiura Gaya and La Gravedad de Coulomb, trio with the flabiolaire Pau Benítez.
