So this has been sold as being for "fans of the three Js" -- James Blake, Jamie xx and Jamie Woon. Needless to say, I was immediately interested.But which J does this mysterious London producer sound most like? At first, I was inclined to say Woon, the soulful vocals carried by a bassy melodic tune. As the song progressed, though, my view switched to Blake, with the interference and spacing bringing him to mind. By the end, I thought Jamie xx, as deep bass cut in and the drum pattern started to sound more and more garage-esque.I'd love to tell you more about this guy, but the truth is I can't, and that's because he's just too elusive. So mysterious, in fact, that we couldn't even find a proper image to put on this post. But anyone who manages to encompass the best bits of post-dubstep's three biggest players has surely got a bright future indeed... so remember where you heard the name first!In the meantime, you can get the vinyl, which is limited to just 300 copies, at Sounds of the Universe.
