I think what he's refering to is, House although influenced from Disco, is not disco. It's Electronic, possibly 100% electronic..., and it's own entity. What Frankie & Hardy were doing with the reel-to-reels, with the disco beats was extremely primitive. The string of releases in 1986-1987 onwards to me really defines what House is. I know that there were earlier releases on Mitchbal, Jessay, and even Chip E's label, but they were nothing compared to what was to come out on Trax or DJ International. The reference to Italo Disco is due to the more electronic sound that those records had, as opposed to Salsoul sound. The Salsoul sound was old and phasing out by this time.
I agree about Gherkin but to say DISCO wasnt a huge part is wrong
House was DISCOs revenge
Love cant turn around is Isaac Hayes / Jack Your Body is a First Choice Bassline
