Scenes from a Memory - 28
This seems low.
Well look at it like this: Regression has only been played live 29 times, so they couldn't possibly have played the the album in its entirely more than 29 times. The reason it's only 28 is because at one show (2/4/2000 Los Angeles, CA) they got shut down before they could play Finally Free. Thus, Scenes from a Memory has been played in its entirety 28 times:
