First was a bit weak for me -- techno part too repetitive for my taste in slower techno (OCRemix has me spoiled, heh) and the swing inclusion just kinda' anemic -- but the second was pretty nice, though it could have stood to be about halved in length

Still, will have to get around to checking out more.
I actually absolutely adore swing (great (great?) grandfather I never met was the drummer in a circus swing band!) and love it when folks tech (if not necessarily tech
no) up music styles, so I definitely like stuff like that.
Contribution:
Peatbog Faeries -- Scots on the Rocks. They basically tech up Scottish folk. Seem to be fairly well known, but a thread search didn't show previous mention... anyway, definitely recommend 'em. They've got some good stuff -- I used "Still Drunk in the Morning" (Couldn't find a good link, bleh) as an alarm clock for a good year, year anna' half.
Then there's
Bajo Fondo which... I'm not actually sure what kind of shape they're in nowadays (got ahold of a dozen or so of their songs back like, a decade ago, been lurking around my playlists ever since), but eh. Near as I can tell they're basically tango mixed with (club) techno. Some good stuff out of 'em.
