"What I'm interested in is a compositional process and a sounding music that are one and the same thing" (Steve Reich, 1968). Minimal music, which numbers Steve Reich among its founders and as one of its most significant representatives, existed for hardly more than ten years. The Ensemble Avantgarde presents a wonderful survey of Reich's minimal music-compositions. The conceptional concentration in the musical work on the structurally simple means of its creation is seen especially in Reich's "Pendulum Music", which is presented here in three different versions. Strict minimal music ended with "Phase Patterns" of 1970. The Ensemble Avantgarde is an association of musicians in Leipzig who are dedicated to the performance of 20th-century music. Since its founding in 1989, the ensemble has worked with a variable membership under the artistic and organizational direction of Steffen Schleiermacher. Concert tours have taken the group through many European countries, East Asia, and South America. Numerous radio productions and CDs document the work of the ensemble. They have been specially recognized through a grant from the Ernst von Siemens Foundation and the Schneider-Schott Prize given by the city of Mainz.
