El Petit de Cal Eril returns with new music and presents a record that, in fact, are three. The triangular cd “Δ” has been produced, recorded and interpretated as a trilogy of EPs, each with 3 unreleased songs and recorded in 3 different contexts. The joint work of all the band has been the key in this new project. The group has valued the connection and the magic generated in the 90 intense concerts of the last tour to record virtually live new songs presented to them by Joan Pons, participating in all the arrangements and the production. A process that has its effect when listening to the entire album, which honors very faithfully everything that was perceived in the concerts of “La força,” because it was recorded in parallel to the tour.
