My failure to catch up with King Crimson on the band’s tour of North America is one of my biggest regrets of 2021. I’ve never seen the venerable prog-rock act. The prospect of eventually attending a concert by the relatively young Charlotte Greve now seems far more likely. The German artist adds Wagnerian excess to the most grandiose elements of prog-rock on Sediments We Move. The extravagant concept album is complex, daring and over-the-top in the best possible ways.
