The Real Filharmonía de Galicia (RFG), conducted by Baldur Brönimann, performed a repertoire of two contrasting musical halves, each 35 minutes long, at the Auditorio de Galicia (Santiago de Compostela). More than 600 biological samples (blood and saliva) of many biological conditions were collected thanks to the collaboration with patient associations and entities such as the Federación de Persoas Xordas de Galicia, AGADEA, Down Compostela, SARELA, COGAMI-CEGADI, ASPERGA, SARAIVA Milladoiro, and educational centres ASPANAES, Eduardo Pondal secondary school, and Rosalía de Castro secondary school.
