One of my all time favorite vocalists is Nana Mouskouri. Seeing her in concert was... alarming. Like Enya, she records multiple tracks of herself singing, a task so difficult to reproduce live that onstage performances are like listening to someone wholly other.
Im not familiar with Nana.
I have nothing againt dubs. But dont call it a live performance.
Mike Oldfield is great.in that its all him thru dubbing. I really dont mind technology. I do dislike cheatery
