^^ I think that might be a tad retro. But I can totally see how they could bring that motif into the 21st century by having an animated LED curtain with the tree, perhaps losing and gaining leaves during the course of the show. One band that took production to the outer extreme is Coldplay. For their most recent tour behind
Xylo Myloto, they handed out LED bracelets to everybody attending the show, and they would be activated/lit up in unison via a remote control. Apparently it cost them about $500,000 per show to do this!
And this is on top of all the other things packed into their show- bouncing balloons, multiple stages, confetti cannons, lasers, dry ice, catwalks, etc. And their tickets were still cheaper than FM.
