“The first time I came to Japan, to Tokyo, it was a transformative experience. It was a powerful and violent experience. It was just like taking acid for the first time - meaning: what do I do now? I see the whole world in a different way. I often compare the experience of going to Japan for the first time to what Eric Clapton and Pete Townsend must have gone through the week that Jimi Hendrix came to town. You hear about it, you go see it, a window opens up into a whole new thing, and you think… What does this mean? What do I have left to say? What do I do now?”

Best attempt to describe it I’ve heard so far.
