[2] His artistic and theoretical work addresses problematic concepts like the relationships between sexuality and music (both understood as socio-cultural constructions, rather than 'natural categories'),[3] or the connections between interactive processes and the illusion of control.
[4] The works of Álvarez-Fernández have been presented in several venues in Europe and America, including the Museo Nacional Centro de Arte Reina Sofía, the National Auditorium of Music and the Residencia de Estudiantes (where Álvarez-Fernández was composer-in-residence from 2002 to 2005) in Madrid, Technische Universität Berlin, The Huset gallery in Copenhagen, Harvard University,[5] New York University,[6] the Eyebeam Gallery in New York and O'culto da Ajuda in Lisbon, among many others.
As a musicologist and sound-art theorist, Álvarez-Fernández has lectured (and his writings have been published) in Spain, Germany, Italy, France, Denmark, Sweden, Macedonia, Serbia, Lithuania, Russia and the United States, among other countries.
For the project "Itinerarios del sonido"[8] (co-curated along with María Bella) fourteen internationally recognized artists were invited (in many cases, for the first time) to Madrid, in order to create a new sound piece that later would be listened to in specific bus-stops around the city.
Participants of this project included Vito Acconci, Jorge Eduardo Eielson, Julio Estrada, Luc Ferrari, Bill Fontana, Susan Hiller, Christina Kubisch, Adrian Piper and Trevor Wishart, among others.
