Is it even necessary to introduce Sigma Project in 2018? "The vast quantity of concerts they have performed, most of them in Europe and Latin America, during its ten-year-old career, the amount of works commissioned during said period, and its participation in six discographic productions endorse its notable role as one of the most active Spanish groups and as ambassador of recently created music” Jose Luis Besada, musicologist (IRCAM, Paris, April 2017). The distinct modularity of SIGMA Project covers from the homogeneity in the formation of four equal instruments to its highest instrumental diversity. This quality is highly valued in the current composition trends. One leaves their concerts convinced of having attended a genuine experience for the senses, where never felt before sensations, the acoustic space and the visual liturgy emerge, all under the characteristic sound that reveals itself as authentic. Sigma Project’s members see themselves as creative explorers that succeed in encouraging the composers who approach their sound, generating new grammars in a genuine sound laboratory. This is shown in the projects developed with the winners of the Spanish National Music Prize, such as Alberto Posadas (‘Poética del Laberinto’ cycle), José María Sánchez-Verdú (Khôra cycle), José Manuel López López and Jesús Torres, among others. This dynamic has resulted in more than 50 premieres so far. Sigma Project’s work is supported by the Instituto Nacional de las Artes Escénicas y de la Música, the Etxepare Basque Institute of the Basque Government and the German Foundation Ernst Von Siemens Musikstiftung.
