Azorín gave the first performance of Old Spain in 1926, and Brandy, mucho brandy in 1927. Ángel Valbuena Prat published in Clásicos Castellanos (1926) his edition of Calderón de la Barca’s Autos sacramentales, El gran teatro del mundo among them. The book included Manuel de Falla’s musical score for the stage performance of this play that Antonio Gallego Burín directed for the Corpus Christi celebrations in Granada, in 1927.

In the field of experimental theatre, Cipriano Rivas Cherif worked with El Mirlo Blanco, a group formed between 1926 y 1927 in the Baroja family’s house by a group of friends that included Valle-Inclán. Rivas Cherif created a new avant-garde theater group, El Caracol, in 1928. Federico García Lorca’s Mariana Pineda was first performed in 1927 (it was published the following year), and revolutionized the theatrical language. The «aphoristic theater to be read», Enemigo que huye, by José Bergamín had its premiere in 1927. Ignacio Sánchez Mejías’ Sinrazón, opened on March 24, 1928 at the Calderón Theater in Madrid, and the play was published in the same year.
