A 56-minute piece for guitar and electronics. It has had a long composition history, starting from a solo for classical guitar and sine tones (premiered in Munich in July of 2010). It was subsequently performed in Seattle (August, 2010), A Coruña, Galicia (May, 2011) and New York (September, 2011). For each performance a new version was created, incorporating recordings from the previous locations (including parts of previous performances), and other sounds that I began to associate with the history of the piece: turntables, radios, records, field recordings, earlier pieces of mine, etc. The process reached its endpoint in December of 2011 (with me recording all the parts on electric guitar). What started as a fairly simple piece is now a densely layered object, that carries its history on its back like a tortoise shell
