I've become a bit obsessed recently, although it's very hard to get hold of. Anyone else a fan? Know any good mixes/tracks/individual artists? Also useful might be places to buy, and places to find out more about it (blogs etc.) might be helpful.

There's a lot of it in this mix: http://blackdownsoundboy.blogspot.com/2010/02/okzharp.html
and I remember Martyn played quite a bit on Rinse a couple of weeks back.

I really love this Dj Cleo track:
