Record Store Day is an international event celebrated on the third Saturday of April which started in a record shop in the USA. The aim is to promote the sale of albums in shops, as opposed to other avenues. This year the number of shops participating has gone up to 60 nationwide, and the releases have gone up to around 400. In Barcelona there will be free concerts all day in La  de l'Apolo, Apolo Store, Disco 100, Discos Revolver and Revolver Records.
