Lothar Baumgarten: Seven Sounds, Seven Circles

This artist's book houses seven CDs that were the audio accompaniment to German conceptual artist Lothar Baumgarten's 2009 exhibition at the Kunsthaus Bregenz in Austria. Each disc contains an hour of audio recorded on a remote peninsula in the Hudson River, the shrieking and croaking of native fauna broken by the occasional Amtrak train. The book opens with photographs and an essay by the artist.
