"...perhaps the way we started to play wasn't as impressive as it was to us, even, wasn't as full of impact as it might have been. I mean, it was done very well rather than considerably exciting. One thinks of it all as a dream." -S. Barrett
The only time I've ever had synesthesia was one time years ago when I took some particularly strong acid. I always thought that was just a cliche, but it really happened.....at moments when I was hearing things, it felt like I was physically being touched. All my senses were being circuit bent.
Sidenote: I met R.D.J. once when my band at the time was playing a festival in Japan that he was playing too. I tried to talk to him, since I dug his music. In short, he was not a cool dude.
