Also, every year, he provides the Foundation with a demonstration of his artistic talent and the international recognition he enjoys.  By offering benefit concerts he is able to raise considerable funds that increase the Foundation's capital and allow us to continue applying our programmes with financial security and independence from government funds.

In 1988, at the concert that marked his return to scene after suffering from leukaemia generous donations were made that created the necessary capital to establish the Foundation. The concert took place at the Arch of Triumph in Barcelona in front of 150.000 people.  Since then, the tenor has offered benefit concerts in cities such as: Barcelona, Verona, San Pedro del Vaticano, Seattle, Lausanne, Tokyo, Nueva York, Roma, Salzburgo, Londres, Solothurn, Vicenza, Neustadt, Detroit, Florencia, Basilea, Montecarlo, Viena, Washington DC, México DF, Pamplona, París, Mannheim, Birmingham, Milwaukee, Aschaffenburg, Saint Moritz, Manchester, Zagreb, Munich, Rotterdam, Madrid, Lech, Atlanta, Escaldes (Andorra), Úbeda, Gars am Kamp, Pesaro, Castelton Farms (Virginia), Edimburgo, Estepona, Cap Roig-Calella de Palafrugell, Eindhoven, Kössen, Altea, Alma Ata, Cheltenham, Guernsey, Sydney, Neuchatel, Palma de Mallorca or Atenas.

Some of the most representative cases are the long collaboration with Chopard, the launch of Doctor Barbie in 1995 with Mattel, the campaign with Vichy Catalán in 1998, the Musical Gastronomy book launched in 2001 or the collection Opera Classics 400 years, edited by La Vanguardia, El País and Le Monde.
