i think people mix up the collective with the label... as far as i'm aware through dealing with them, the collective help out with getting distribution, artist bookings and so on. But the labels are definitly seperate.

suf - chris, aaron, julien, paul harding
cluster - liberators
4x4 - julien
hydraulix & apex - d.a.v.e.
powertools - ant
hazchem - ddr and (more recently) sarah....

blah blah...

but a lot of people do confuse the "collective" with the label.
