Thanks, Andfurthermoreagain. You can do no wrong by picking up ELEMENTS 1970-1971. As well as the 2CD of ALCHEMY on Cherry Red. It's really engaging stuff.
Interesting you mentioned how "Overture" reminded you of something on JEHOVAHCOAT DEMOS. I hadn't clocked that. But having just re-listened to it, it does seem to have a BLACK MATH vibe to it, as well.
