The Orchestra has already recorded more than forty albums. Its discography includes a Basque music collection, supported by the Mondragon Group, which has become a benchmark and reflection of how the Orchestra promotes Basque symphonic heritage, monographic works, children´s music or recordings of works by authors from different origins, from Basque singer-songwriters to internationally renowned composers. Many of the Orchestra's albums are collections of works which have been recorded for the first time, such as the opera entitled Gernika by Francisco Escudero, one of the highlights of Basque musical creation in the 20th century.
