Michael, please don't let the idea drop. If the vinyl revival is real (and most people think that it has moved beyond any thoughts of it just being a fad) then, as the future depends upon the availability of lacquers and the as the revival has already involved large investments, surely the finances must be out there? However who can make perfect flat aluminium (I'm British) discs?
Now for cutting stylii!
BTW, the old EMI plant is now housing/gym/restaurants & bars/shopping and a live music facility.
