This is a group totally new to me…and Custard Flux is described as heavy acoustic driven Prog-Psych-Pop. For those of us of a certain vintage this will seem familiar and a bit comfortable.
Here is their latest release that just came out July 3, 2020. It’s only audio: Oxygen. This is their band camp page and Oxygen is currently topmost.
And if you want to see some Prog Psych visuals to go with the music…have at it!
