Well, he also wrote music especially for the movie Happy Feet, so maybe it's not such a shock that Prince will open his own nightclub in Las Vegas and, of course, play the occasional show there. From Billboard.com:
A flash graphic on the Web site 3121.com, named after the artist's most recent studio album, includes the Rio plus photos of Prince and such artists acts as Sheila E, Maceo Parker, Floetry, Patti LaBelle, Esthero and Cee-Lo, although it is unclear what connection they have to the endeavor.
It is also unknown how regularly Prince plans to perform at the venue formerly known as Club Rio, which has hosted a topless revue called Club Eroticka since February 2005.
Hey, maybe he'll turn his ass-kicking guitar solo followed by disappearing guitar into a regular gimmick.
