There are at least two projects with the name Synodic.

1) Synodic is a project focused on actual science of the cosmos.
Founded in 2017 by Tulsa, Oklahoma-based multi-instrumentalist
Myrdin Cerphas and lyricist and conceptual artist Imber, in their own words this cosmic black metal band
aims to be “a factual portrayal of the universe through the music”.

Imber brought forth the idea of creating Synodic in early February of 2017
after listening to certain albums in cosmic black metal
and seeing there was an absence of factual science in the music others created.
Since Imber and Myrdin lived together it was an easy idea to work on in their own time.
After writing the lyrics and creating the concept for Prodigious
Imber then departed Synodic due to conflicts between Myrdin.

Drawing inspiration from the late astronomer and science
communicator Carl Sagan, Synodic “hails Sagan rather than Satan”,
and goes as far as taking one of the scientist’s quotes as a motto:
“Our imagined self importance, the delusion that we have some
privileged position in the universe, are challenged by this point of
pale light. Our planet is a lonely speck in the great enveloping
cosmic dark”. Portraying the science of astronomy through music,
Synodic “brings the reality and feeling of the universe together” in sound.
Distancing from the contemporary black metal scene, Myrdin tries to keep Synodic
“basic and stripped down, but still expansive in atmosphere”.
