Bajañí is the name for the Spanish guitar in Caló. Taking this instrument—and specifically the guitar and artistry of Niño Josele—as a starting point, Fernando Trueba invites viewers to experience music as never before. It is a new musical journey within his filmography, traversing three musical worlds—flamenco, jazz, and Brazilian music—where Niño Josele and his guitar engage in musical dialogue with Caetano Veloso, Ron Carter, Rubén Blades, Kenny Barron, and Marisa Monte.
