Excellently observed and reported Guardian feature on Jackin' House by Dominic Morris, aka Datwun aka Musings of a socialist Japanologist .

Thesis: this Northern mutant of house + bass =  rave reborn.  That includes an E-induced loved-up not sexed-up vibe:

"Rather than any unsolicited grinding, the only mating ritual I saw all night was when I saw a muscle man miming an exaggerated bench-press to a girl watching with arms-crossed, an arched eyebrow and a playful half-smile."
