At long last, and/OAR presents the second of a series of limited edition collections illustrating the various approaches to environmental sound art. These collections allow for longer format works to be presented within a multi-artist presentation. Also returning for the first time in five years is the custom card stock insert packaging housed inside clear vinyl sleeves. Yperiau, by French sound artist Eric Cordier, is a sonic exploration of the lower regions of the Maison de Radio France in Paris, where its own power plant is situated. The huge building is virtually a city within the city equipped with recording studios, performance halls, a cafeteria, restaurant, clinic, museum and gymnasium. Scott Sherk is an American sound artist who recorded and edited sounds of a train yard near Allentown, Pennsylvania. Some of the frequencies captured proved to be a bit too intense for the microphone used to make the recording, so certain sonic artifacts emerged as a result. Elsewhere in the piece, there were some fine tuning of harmonics using a Max/MSP patch created by Scott. This release is limited to 200 copies
