A meeting of titans. On one side the Catalan duo ZA! and their globetrotting music, in the confluence of rhythms coming from noise, psychedelic rock, free-jazz, electronics or post-rock; on the other the Andalusian singer-songwriter Perrate, one of musicians that has been opening the space sound of flamenco, through the influences of reggae, bolero or rock. The collaboration was created has a response to an invitation from Música y Museos cycle, an initiative within which they began to experiment with the creation of completely new sound universes. Polyrhythm and surprise, improvisation and tension are some of the key words to define this concert.
