Madonna's MDNA tour stage has the largest LED screens in touring history and Gaga's BTW Ball tour castle is the largest scenic structure ever built to tour.
Even though I prefer Madonna's gigantic LED screens, I'm more impressed by the BTW Ball stage. More interesting and something never seen before in touring history. LED Screens are nothing new.
And there is something special about big screens, especially in madonna's case, because she does things with them that have never been done before. the effects are amazing.
The castle is not very interactive for a concert, on concept looks great but in reality is very monotonous.
The MDNA stage gives an incredible experience for each song of each segment, not to mention those amazing elevated blocks who create secondary stages like in GGW and Celebration.
