Naxos has released 14 of his songs under its Spanish Classics title. Madre Asturias is a collection of songs written in 2004, which feature tenor Joaquín Pixán with Rosa Torres Pardo on piano. Listening to these songs, it is very clear that Abril has given the piano as strong a voice as that of the singer. Together, they create an unusually powerful musical instrument with which to give us the full impact of the musical heritage of Asturias through the composer's personal perception.

There are love songs, melodic dances, a lullaby and the very last, a song that expresses the nostalgia and love that Asturian emigrants feel for their homeland, hence the title of the CD album, Madre Asturias (Mother Asturias).

While on a Spanish theme, naïve, under its Esprit label, has released 16 songs by a variety of Spanish composers that include Falla, Albéniz, Rodrigo and Granados. Simply titled Ibérique, these songs are often flamboyant, evoke the typical image we all have of Spain, yet are musical expressions of a very classical nature. Musical heritage consists of a wide mixture of influences, including that of ancient Visigoths, the people of Byzantium, those from Mozarabia, Berbers from Morocco, settlers from former Judea, and the Gypsies from India. They all brought their music with them to create an exotic mix that to this day can be heard throughout the Iberian Peninsula. What's more, the country's most famous operatic singers have never shied away from singing this music, which is represented by both popular songs, balads and so-called 'art music', such as Abril's compositions.
