“Hrrrg. There's a bit of a story to this one. With This Is My Jam wrapping up shortly, I wanted to post something super-weird, and immediately thought of King Crimson. After a struggle to find the 9+ minutes version of the original, I found a chiptune cover, and I quite like it. The YouTube uploader did not include a credit with the video description, and I'm not sure if it was made by them or someone else (hence the "Unknown").
Anyway, it's pretty gnarly, and definitely fits the bill for "weird".”
