DO-UNDO. 4th to 7th of october 2006. Residence working in Q-O2 project "Do Undo Recycling G" in Aalst, Belgium. http://www.netwerk-art.be/ Several musicians recomposed material played by Julia Eckhardt (viola) and recorded by Ludo Engels. Lucio Capece composed and played a piece for soprano saxophone and a tape built with Julia´s sounds. The saxophone was played filtering the sound in different manual ways. The tape was played in a fragmentary way by sources of different fidelity (DAT, CD, cassette, Mini Disc) and amplified by speakers of different qualities in several points of the space. The piece was called " Fi- Space Filtering". Thanks to Netwerk and Q-O2. Less
