<p>Zwei Frankfurter Prludes [Two Frankfurt Prludes] presents a live recording of the twos premire given on November 19, 1999 with the hr Sinfonieorchester conducted by Arturo Tamayo. <p>The titles of these works are nearly identical (1. "Two Cranes and Clouds" and 2. "Two Cranes and Clouds / Double") and are conceptually related, though they could hardly be more different. One is based on an extreme accumulation of density over about a minute and a half, while the other explores a radical expansion in both time and space. Each work is scored for large orchestra and the second of them, which lasts some 50 minutes, positions the musicians along a diagonal line that bisects the performance space.
