It was a real pleasure to have Sigma Project in the program of the Ciclo de Conciertos de Música Contemporánea of the BBVA Foundation in Bilbao once more. They performed an impressive concert that included two wonderful world premieres by Alberto Posadas and the young composer Helga Arias. It was an unforgettable concert for many reasons. My most sincere congratulations to Sigma Project!
