Alejandro L. Madrid is the Walter W. Naumburg Professor of Music at Harvard University. He is a cultural theorist of sound and music working in Latin American and Latinx studies. His nine books and a host of distinguished articles have established him as one of the foremost musicologists of his generation and one of the leading scholars in Ibero-American music studies. His work, which engages popular, folk, and art musics from multi-methodological perspectives, has been described as a “model for future works that aim to cross boundaries between musicology and ethnomusicology” and as “scholarship that intervenes in a number of important critical conversations.” He is currently writing a book about sound archives and the production and circulation of knowledge at the aural turn entitled The Archive and the Aural City: Gimmicks, Networks, Utopias, and the Logic of Archival Knowledge at the Sonic Turn; and a book about Silvio Rodríguez’s influential Nueva Trova album Días y flores. He is also working, in collaboration with the Momenta Quartet, on a 5-CD recording project of the complete works for string quartet by Mexican microtonal maverick Julián Carrillo for the Naxos label. In 2015, he published the book In Search of Julián Carrillo and Sonido 13.
