Audio-CD: Planetenmusik / music of the spheres is the cooperation of Brian Cranford, Tobias Krug and Hartmut Warm.
In August 2001 Hartmut Warm published his book „Signature of spheres / Maintenance of order in the solar system“ which is dedicated to the analysis of texture of motion, layout and harmonic connection in our solar system.
In November 2002 Tobias Krug and Brian Cranford started the project „Akustik-Clock“. Here there is the artistic-scholarly debate with the interplanetary rhythms of the solar system.
2006 Brian Cranford established the label „Indiscreet Cosmos Recorder“ and in the same year he published the CD „Akustik-Clock / musical siderale“ a combination of conclusions up to this date.
