Now Man Like Kristian says this music is actually heard at its utmost in the mix, and directed me to these mixes. The first, by Spooky, works with Vol 1, and was done for his Deja FM show. The second, by DJ Tempo, works with Vol 2 + some new Footsie beats, and was done for Big Dada
King Original, incidentally, was the name of Footsie's father's reggae soundsystem, which prompted in me the thought that, for all the flak I got / get over the Nuum, it really is not just a genreological continuity but in quite a few cases, a genealogical lineage. Father to son, uncle to nephew... many crews that contain brothers or cousins. Mostly male-to-male: a fratriarchy, yes. But not always. One good counter-example I came across was Mz Bratt, the female MC whose dad was MC Scallywag (as in Spiral Tribe, as in the voice on that 1992 harcore tune by Grant Nelson under the name Xenophobia, "Rush in the House")
Here's a Youtube interview Footsie talks about his dad's influence on him.
