L´OEIL (sax quartet & electronics)

"I arrived in Mexico city and was whisked off to a concert at El Colegio Nacional. It was the spanish quartet of 4 saxophones Sigma Project playing the world premiere of Alberto Posadas’s new three piece cycle 'Poética del Laberinto'. This was wonderful opportunity to catch up, with the magnificently accurate, inventive and awe inspiring performance by the spaniards. I thought this sort of precision could come only from a quartet of strings".
