Welkom to the sound worlds of 33 Tetragammon & Apollonius/Human Metronome.


Our music is a reflection of our descent into the inner realms of the Self. It contains more than sound: interweaved with the melodies and drones is a consciousness that guides the listener to deeper states of awareness. Enjoy this universal ride!

You can listen and buy our albums on Bandcamp. Our music is also available through CD Baby, iTunes, Amazon, etc.

The Observer (5-3-16)

It’s been awhile since my last message. Somewhere in 2015 I stopped making music. It just wasn’t out ‘there’ anymore (I know it will be back at some point, though). I finished some older work but didn’t feel the passion to master it. That year had been all about my other passion: painting. But always with some good ambient music accompanying me from the likes of Robert Rich, Oöphoi, Bach and some Steve Roach and Alio Die. It’s been a good year to deepen my artistic skills and present myself and my work to a larger audience.
