Sure, it's a production, but there are musical performances within it ... I don't think it takes away from their talent ...
I think I know where you are coming from - when I go to the Newport Jazz Festival, I am seeing 'musical performances' ... when I go to a pop or rock concert, I am seeing more of a production ...

when I close my eyes listening is the main thing....
how the magic happens can always be heard...
show business is a wonderful thing to transport the audience to anther place.
As technology keeps growing new things in music will continue to change ...

embrace it I say...
