Gracia jazz sessions in Barcelona

Gracia's jam. Every tuesday you have an appointment with the best jazz musicians of Barcelona, the ones that are temporary here or the residents. There is a band that opens the concert, then the musicians in the audience go to the stage to play, they don't know what are they going to play, for shure is going to be fine. Improvisation is the key. A night that is always different as every interpretation in jazz.
