Seijiro Murayama is a drummer-percussionist-voice performer currently working in Japan again after living for a number of years in France. Éric La Casa is a French sound artist well known for site-specific field recordings with a strong improvisational element. The two have been working together on numerous projects for nearly a decade. For six months starting in January 2012, La Casa and Murayama took portable tape recorders out to parks, subway stations, streets and other public spaces in Paris and separately made individual recordings in the same place and time frame, then edited the recordings. The result is the 12 tracks on this CD. Murayama frequently produced his unique vocal sounds while recording. This odd and unexpected voice sneaks into the varied and lively sounds that fill the public spaces, creating curious accents.
