In the beggining, Als Eco was formed by Adriana Vásquez, Eduardo Caicedo, and Antonio Correa. Nowadays, there are many more musicians in their ranks.
Als Eco is devoted to the performance of contemporary music, especially to the so called minimal music. In its repertoire there are works by significant contemporary composers such as Simeon ten Holt, Steve Reich, La Monte Young, Terry Riley, Philip Glass, Jacob TV, Louis Andriessen, Marc Mellits and David Lang, as well as pieces composed by some of the ensemble members.
Als Eco believes that the tendency to relate one sound to another is not a man-made invention but rather a law of nature. Als Eco is not interested in playing “interesting” music. The only concern of the ensemble is to perform music that does not make reference to the unbreakable barrier between the composer and its audience that so many recent compositions have managed to build.
The Als Eco Ensemble has premiered in Colombia Simeon ten Holt's Canto Ostinato, Lemniscaat, and Incantatie IV, Louis Andriessen's Workers Union, Philip Glass's 1+1, Two Pages, Music in Contrary Motion, and Music in Similar Motion, Michael Gordon's XY, Jacob TV 's Off and On Situation Blues, David Lang's Sweet Air, and Marc Mellits', Disciples of Gouda, and Evan Ziporyn's Where was I?, among other works.
About Als Eco XL
Anytime Als Eco's original instrumentation and/or number of performers falls short for a particular piece of music the ensemble calls upon additional forces, specifically suited for the tasks at hand, thus becoming Als Eco XL. Recent activities involving Als Eco XL include Terry Riley's In C, Louis Andriessen's Workers Union, David Lang's Sweet Air, and Marc Mellits' Disciples of Gouda, as well as improvisation concerts featuring the Swiss improvisation ensemble Grand Reportage. Future projects include the live realization of Brian Eno's Music for Airports, Tight Sweater and Paranoid Cheese, by Marc Mellits, Evan Ziporyn's Where was I? and Terry Riley's Keyboard Studies 1 and 2.
