Just updating this.
We recorded on Saturday, at their home base (our singer is friends with one of the owners)
Really good quality setup, hard disk and Pro tools setup, the engineers are really nice blokes.
The isolation booth is a bit small, so our drummer had to go into a seperate room, but he uses a huge kit, most drummers should fit inside the caravan.
It is incredibly dead in there. I've been in some dead rooms, but that that thing is incredible.
We will going back to do vox and pixie dusting the track, then i'll up load for you guys to hear.
All in all, one of the best studio experiances i've had.
