It's really difficult to pin down who exactly the audience of jackin is. When you go to 2:31 everyone's dressed pretty hipster/studenty, when when you chat to people they all seem to have pretty normal service jobs and that. Also I get the vibe that shuffle is more of a black thing than jackin, which is maybe like 80% white or something.
That 2010 Leeds sound has been dead since 2011! If you mean tracks like James Oliver - Doin Time, Jayye Jackin - Oh Baby, Lorenzo - Love For Me. That really bouncy basically-still-electro sound long ago morphed into Jackin proper, with all it's many facets.
I don't know about Audio Rehab in particular, but the thing about a lot of this shuffle house is its so un-pop that I find it difficult to see it throwing up many cross over hits. Unless it's stuff like this:
This really confuses me, is this part of the shuffling scene? Would it get played in deep-tech sets? The video's all clips of people shuffling (nicked from the Melborne stuff I reckon), but it doesn't really sound like anything else in this thread. I totally love it! It's like those future garagey emo cut-up vocals put over a beat which isn't totally anaemic. Second drops mud as well. If there's more shuffling like this I'd love to hear it!
Back to shuffle vs. jackin though, I'm not saying you're wrong that it could be shuffling that blows up not jackin - though I'd love to see jackin get its dues nationwide I'm not holding out too much hope - but I'm interested in why you see the shuffle stuff has more 'promise', unless you mean it's less good so it has more room to get better lol.
For me the thing with the shuffle house is that it's so very very similar to a lot of house that has existed for 10 years. People laid into me for claiming some kind of novelty for jackin, but it's easily 10 times more different from it's predecesors and more innovative that this deep-tech house. Even if you can claim that jackin has no brand new ideas of its own (though I think anyone who can't hear the innovation in the basslines simply needs new ears), at the very least its a new configuration of all of its influences. With shuffle house I don't even think you hear people claiming any novelty for it, more like it's the same tech house as before but more interesting because of that London darkness.
