I just received and played the “Gammadrone” CD. It is exactly what I expected and wanted. I am a writer and have it playing as I work. It allows me to focus on my novel and use it as a barrier to the world’s noise. Thank you! Please keep me informed of the next development of your important music.

W.A., Amazon customer review of “Gammadrone”

Not “music” per se, but serves it’s purpose. Solfeggio frequencies can be grating to my ear, but this recording is suitable for me. I like to play it in the background while I read or relax. I have other J.S. Epperson recordings and I find his compositions and some of his other recordings perhaps are more melodic, but for the price and purpose this does it for me.
