WARNING: Music plays as soon as you enter this site.
We went a couple of weeks ago. You can probably be in and out of there in about an hour. It depends on just how much of it you want to read and watch (they have videos with interviews, etc.).
I love the band. Pink Floyd (Dark Side of the Moon and after), Mozart and sometimes Bach are my favorites to "get into flow and stay in flow".
