Speaking of which, Check out this interview. It's 2 hours long and I am only 20 min. into it but it's quite fascinating. David is quite a guy and he sounds like he is such a wonderful artist by accident. "I have no idea why that happens"
I too have been watching it, very informative and just plain neat. That is how I ended up down the Pink Floyd rabbit hole the other night. Resulting in all communication devices taken away! Hah!
