(spin-off post) arXter made a thread about Mike's beautiful back vocals... And I'd say, among female R&B artists, Faith Evans knows a thing or two about doing back vocal. Hers is sophisticated and layered. Simply beautiful. Many singers start off their career doing chorus and/or back vocal and she is not an exception, but not all of them have the skill. So, I think she can make a lovely duet with MJ and we'd hear fantastic back vocal done by both. They can do just about any type of songs, but she can easily take the place of Marsha for a track like Butterfly. Just an idea.
