I didn't know Heilung--it's the sort of complex, textured music that I like. I can see why they have such devoted followers.

Most of the music of The Three Suns is easy listening; anything arranged by Charles Albertine is more adventurous. I had considered suggesting this version of "Poor Butterfly" (from Gilbert & Sullivan) mashed up into "Flight of the Bumblebee" (Butterfly on accordion and later organ and guitar, the menacing Bumblebee on violin): https://youtu.be/Nikoe-Y5BJg

One of my favorite musical jokes.
