Madrid-born Eduardo Costa Roldán, has premiered more than thirty chamber and symphonic works. Composition of educational materials is one of his main creative concerns. Tempo de Huida and Berlín 1928, two of the works included in this album Perfil del aire, were born with a clear didactic purpose. The other four titles (Diálogo de sombras, Tríptico, Escenas de la vida de Poulenc and Dos imágenes) were commissioned by renowned flautists. Julián Elvira is Spain's leading name in experimental music for the flute, both from the performing and academic world. His comprehensive classical training, his commitment to the performative component in his projects, along with his attraction to the sounds of different cultures, make Elvira a unique flautist. Sofya Melikyan, brings her expertise on the keyboard as well as her aesthetic affinity with Costa's musical expression. Trained in her native Armenia and later in Madrid, Paris and New York, Melikyan values rigour, technique and great expressiveness in her interpretations. A collection that allows us to get to know the author's different creative stages and his varied profiles through the flute. As Luis Cernuda writes in his first collection of poems, from 1927, entitled Perfil del aire (the book from which the composer has taken the name of this album): "Guardada está la dicha / en el aire vacío" ("Happiness is enclosed / in empty air").
