"Re-creating" Glenn Gould's 1955 Goldberg Variations

There has long been a tradition of trying to improve the "sound" of old classical recordings for the market. Some labels actually specialise in this practice. Usually, this involves minimising the background hiss and/or making the recording sounds "stereo".

What if there is now a totally new approach, one that relies on technology to "re-create" what it sounded like when, say, Glenn Gould recorded his legendary 1955 version of Bach's Goldberg Variations? Could this claim be too good to be true?

I have to say I am curious about how good this new technology is and whether it really can bring Glenn Gould back from the dead, since the 1955 Goldberg Variations is one of my all-time favourites.
