Prices range from 38 euros to 80 euros, with tickets to go on sale on the website barcelonaambvalencia.cat from 12 noon on 12 November. Those interested in collaborating without attending the concert can purchase a ‘row zero’ ticket at a symbolic price of one euro, plus whatever donation they would like to make.

The poster for the concert is the work of the artists Santi Moix (illustration) and Isabel Ramoneda (calligraphy).
