Los Primeros Fríos: There are two versions of this piece, one in marble and one in bronze. The marble version can be found at the MNAC in Barcelona, and also at the botanical garden in Buenos Aires, while a bronze version can be found at the Museo Regional de la Garrocha, in Olot. The two versions mark two different periods of his sculpture. The marble version is idealistic, focusing on the contrast in detail between the wrinkled skin of the old man and the smooth, tight skin of the young girl. The bronze version is more influenced by the works of Rodin, and is a synthesis of realism as well as the emotion evoked by the two characters. Its modernist technique influenced an entire generation of Catalan sculptors. ;
La Canción Popular Catalana: In 1905, Blay was approached by Modernist architect
Lluís Domènech i Montaner to create a group of sculptures for the facade of the
Palau de la Musica Catalana, a concert hall in Barcelona. The building is known for its
Art Nouveau style and is made up of a mix of glass, metalwork, sculpture, and ceramic mosaics. Miguel Blay created a group of sculptures titled “La canción popular catalana” (The Catalan Folk Song) for the facade of the building. The sculptures depict different characters of varying social classes: children, peasants, sailors, etc. In the center, there is a female figure that represents the Catalan song. Above her the patron saint of Barcelona,
Sant Jordi, stands holding a sword, protecting her and the other sculptures. It is said to show that people of all classes can enjoy the traditional Catalan music. ;
