Rafael Aguirre is one of the most sought-after guitarists at an international level, having received First Prize at competitions such as the Tárrega Competition while obtaining relevant awards in all instrumental categories—such as the New York Pro Musicis. He was named Associate of the Royal Academy of Music in London (ARAM) in recognition of his international career.

He has performed in 43 countries and continues to add high-level performances to his resume, including performances at Carnegie Hall in New York and the Boston Celebrity Series. He has previously performed in venues such as Concertgebouw in Amsterdam, Verbier Festival, Konzerthaus in Vienna, Tchaikovsky Hall in Moscow, King's Place in London, Hyogo Performing Arts Center, Seoul Arts Center, as well as in many of the leading venues in Spain.

With a solid classical training, the result of the inheritance of the tradition of Andrés Segovia and Narciso Yepes, Rafael Aguirre has multiple musical interests, performing with an ensemble of musicians from the Berlin Philharmonic, the pianist Lang Lang, the sopranos Fatma Said and Hera Hyesang Park, regularly with the cellist Nadège Rochat and many others. He is also committed to expanding the repertoire of his instrument, working with multiple living composers and also including in his performances flamenco, Latin American, and Spanish popular music—and even reaching pop and film music.

As a result of this recording work, he has received enthusiastic reviews from Gramophone, The Strad, and Crescendo Magazines, as well as appearing on international radio programs such as the BBC, NPR, CBS, Radio Stephansdom of Vienna, Radio Berlin Brandenburg, HR Hessische Rundfunk, Bayerische Rundfunk, NDR, MDR, Radio Nacional de España and Toronto's The New Classical FM.
