Grupo de Música Antiga Martín Códax is one of the European referencial groups in Medieval Music interpretation, with a twenty-year career dedicated to the study and performance of music written from the Middle Ages to the Renaissance, especially the XII, XIII and XIV centuries. The group's name pays homage to one of the most important representatives of the Galician-Portuguese lyric, the troubadour from Vigo Martín Códax, with his seven cantigas (songs) as part of the repertoire performed by the group. The group has performed numerous concerts in music series and festivals, both in Galicia and in the rest of Europe: Festival intercéltico de Cangas, Festa da Istoria de Ribadavia, Festival Espazos Sonoros, Fine Art Museum of A Coruña, Festival de Música Antiga de Palma de Mallorca, Festival de Música de Palencia, Festival de Cuenca, Auditorio Nacional de Madrid, Instituto Cervantes in Roma, Castell de Peralada, National Germanisches Museum in Núremberg, Musikinstrumentenmuseum in Berlín, Victoria & Albert, among others. In 2000, Martín Codax collaborated with the bagpiper Carlos Núñez in a project to recreate medieval music with instruments of the Pórtico de la Gloria. He also collaborated in several projects with the Galician publishers Galaxia and Xerais for the promotion of medieval literature. The group Martín Códax is also working with the Galician company Bodegas Martín Códax S. A., in an intense task of foment and promotion of culture and medieval Galician-Portuguese lyric.
