Not the biggest fan but last year whilst on a trip to the USA I was persuaded by my wife to take a trip to Minneapolis and have a guided tour round Paisley Park. Thoroughly enjoyable day and he had (still has) some serious recording kit there. His 2 main studios are bristling with superb equipment and technology, and the enormous sound stage is fabulous. If you ever get the chance go there. Don't go in winter though as its ruddy freezing! We went in summer. Short 30 minute taxi from downtown Minneapolis.
