According to Billboard.com, R&B superstar Prince is in the process of opening a nightclub at the Rio hotel in Las Vegas. The new club will host personal performances from Prince as well as acts signed to his NPG label. Sources tell Billboard.com that Concerts West/AEG Live, producers of Prince’s $90 million Musicology tour in 2004, will be working with the artist on the project, which will launch next month. On the web site 3121.com, named after the artist’s most recent studio album, there are photos of the Rio, as well as of Prince and Sheila E, Maceo Parker, Floetry, Patti LaBelle, Esthero and Cee-Lo among others, although it is not yet clear if and when these acts will be involved in the new venture. Meanwhile, Billboard reports that the singer’s new track ‘Song Of The Heart’ will be featured on the soundtrack for the new animated film ‘Happy Feet’.
