Soundwalk is an international sound collective founded in the early 2000s by Stephan Crasneanscki and based in New York City. In the summer of 2011, the collective retraced Medea's mythical journey along the coast of the Black Sea, collecting fragments of voices, music, Morse code and ambient sound, collaging them into a work of sound art. The book follows the sound composition of the CD (included here) and also gathers photographs by Stephan Crasneanscki and texts by Arthur Larrue.
