Is it a bookcase...or a musical stage to perform on?

I wish I was in Belgium during a recent dance music festival.  The stage looks AMAZING.  If I was a performer on that stage, I'd feel like a character in a book come to life:

Isn't that incredible?

I seriously want to go to Belgium and see that before they tear it down.  

And check out the name of some of those books!  I especially like THE BEAUTY AND THE BEAT in the far left.  It's music-related AND book-related. SCORE!!
