Couple of points to make.
Packaging - The Fabric cases are wicked but I like what GU did with the Lawler case. black rubber + velcro! ooooohh
As for the actul music content, I have to say that when GU started, it was like a breath of fresh air. The two early Oakenfold offerings were superb imho. Or at least they were to me. The GU series is what opened my ears to the more progressive sound. I still to this day have a little bit of a fascination with collecting all GU offerings.... which is where Fabric have nailed it with the subscription idea - Genius! The GU series seemed to then slip a bit and didn't come across as essential purchases, but at the same time the NuBreed offshoot started up which I think has thrown up some beauties. I think the idea of using slightly more underground djs for the Fabric series' has paid off wonders, Tyler Stadius' latest is a prime example. I really want to catch this guy now. I know what sound to expect from the big boys so missing a couple of their mixes doesn't bother me too much.
Another point to be made is that GU place the emphasis on mixes inspired by certain parts of the world - Fabric's are the sounds of London, now.
In conclusion, I reckon if GU carried on in the slightly more sexy packaging vein, offered a subscription service (once evey two/three months? Can't think how regularly they throw them out) they would be back up there. But at the moment my Fabric and especially, FabricLive cds are the ones that are gaining most mucky fingerprints.
'Course if GU got a Boshin'n'Bangin' series going, I'd be there!!!!! Me Julesy, Pearcey, and the new boy from Holland - Hertz Van Rental......
