This is pretty crazy man. Was just explaining to my wife the other day about Aphex's history and how he hasn't released anything for a long time and how the fans got the kickstarter going to purchase the test release of Caustic Window.
Now today there are blimps flying around and stencils showing up around NY etc with his logo on.
Does a blimp and graffiti campaign seem characteristic of anything Richard would do? No established record label, in their right mind, is going to endorse a an ad campaign involving tagging or any other minor offense for that matter. Furthermore an enormous green floating in the sky Aphex logo seems like the last think RDJ would get behind.
That blimp shot looks fake to me too but I'm no expert in photo analysis.
