Further Materials is a follow up to 2002's Other Materials. Both are collections of non-album tracks which originally saw the light of day on compilations with like minded artists. Richard Chartier is a sound artist, installation curator, and sometime lecturer who needs no introduction to anyone mildly interested in electronic music. He is one of the originators of the "microsound" or "lower case" form of digital music, which is, as it sounds, minimal music, usually played at minimal volume. What's intriguing about Chartier's music is that if you listen carefully, and with the volume pegged to ten, there's incredible depth to his music.
