I don't know if it's prog, but Stoiko Todorov's (CR senior programmer) brother's band has Bulgarian bagpipes:https://smallman.bandcamp.com/
On the heavier side of prog for sure, sounds good though. Bookmarked!
How about that, Porcupine Trees ex drummer
Heard of them, never checked them out though, cheers for the links. Anything that has been touched by the god like hands of Steve Wilson has to be good though, even if it is just production.
It appears to me there are two sides of Opeth - the earlier microphone eating and throat gurgling, and the later proggy stuff. Heard snippets from both, did not enjoy what I heard. Perhaps I should give them a proper listen.
I wonder if it is a bit like the way Dream Theater went - loved their stuff when I got into them in the late 90s, Awake, Images and Words, Metropolis Pt 2, Six Degrees of Inner Turbulence, but then something happened after Six Degrees, it lost it's magic.
