DJs really become popular in this scene when they produce hits. People get to know a DJ first through their productions, and then as a DJ. But I have seen it a lot....great producers start DJing to make more money, and just aren't good at it. Somebody brought up James Holden....I totally agree. I think his productions are as good as they come, and his track selection is on point too. But damn, he needs to learn how to mix. I have a ton of his recorded live sets, and the mixing in all of them is just bad. But his productions are amazing, and people (including myself) go out to hear him play live every time he comes around.
