Right here, right now, the solid Earth is moving under your feet. Earthquakes, storms, and ocean surf on a distant shore: each contributes a note to the restless chorus of vibrations that echoes across the planet’s vast interior.
The CD includes three 20-minute recordings of these slow natural vibrations, captured by a global network of digital seismographs and transposed into high-quality stereo.
The CD is accompanied by a 16-page full-color illustrated explanatory booklet. Here's a free PDF of the booklet.
An excerpt from this CD was featured on NPR’s “Sound Clips” series in 2006.

Note: this CD was re-issued in 2010 with a new package design and some minor corrections to the text of the booklet. The audio is the same as the original 2007 edition.
