exclusivity doesn't benefit a scene in the long run, but certainly boosts the careers of djs that are in on the monopoly - at least thats the way it worked in jungle. i don't think thats the reason with dmz et al, but its still frustrating not being able to get this great music.
Its pure speculation of course, but I think that dmz have a very real understanding of the value (non-monetary of course!) that can be brought to their music through holding off releasing it. For example, the track Changes, in my opinion the most majestic, ethereal and defining dmz track, has never been released. I cant imagine that this is because they don’t think its good enough, nor that they just rate other tracks more highly. But because its never been released, and my primary memory of it is of darkened smoky rooms filled with bass pressure, it retains so much that might otherwise be lost if available on a tangible object available from all good retailers. For me, that track now actually embodies that whole time in the development of the music… the point where dmz, who I believe will be remembered as the dubstep crew, came into their own. And I think a lot of that magic would be lost if I had it in my hands on a mass-produced piece of plastic, being dropped by every sub-standard dj in the land. I would be genuinely disappointed if it was released now. And I think that there is an aspect of their thinking that while they want a lot of people to hear their music, they want to keep that impact and magic, at least for a few key tracks.
and we still have them on mixes
