Iterationen ("Iterations") is a musical experiment that juggled artistic processes. How does music resonate through other music? What happens when the game of Chinese Whispers meets a dynamic feedback loop? In a live concert in Berlin, Ensemble Extrakte -- a trans-traditional ensemble led by Sandeep Bhagwati that unites musical folk, jazz, and art music traditions from India, Korea, Syria, China, Bulgaria, Armenia, the US, and Europe -- plays to music in their headphones: they interpret pioneering techno and electronic tracks put on by Berlin-based Brothers Teichmann (or Gebr?der Teichmann). But definitely not in the sense of "Beatles go Classic": they do not simply echo the melodies and harmonies, rather, inspired by the energy and playfulness of the tracks, they improvise a resonant response, transforming and filtering the electronic sound they hear through their traditional instruments and musical expressions. The DJ and electronic music duo Gebr?der Teichmann then feed this concert recording into their electronic laboratory, using their electronic ears, their instruments machines, and computers to discover a new layer of resonant responses. They reverse, enhance, re-compose the improvisations of the Extrakte musicians, finding new connections in their sounds. Iterationen is an ongoing project, a creative love affair between traditional and electronic music making -- this album is the second step. All compositions and improvisations: Ensemble Extrakte; Working scores: Sandeep Bhagwati; Remixes, edits and reinterpretations: Gebr?der Teichmann.
