This has less to do with review and more to do with context.
So a few minutes before the show started, someone made an announcement over the loud speaker warning the crowd "not to eat the brown doughnuts, If you eat the brown doughnuts please report to the Waterwheel table". Now this got a great laugh and cheer from the crowd and then I didn't really think about it.
The boys come out and play the first set. Set ends and my buddy next to me days that he thinks they are playing with the trippy brown doughnuts (acid) theme. The water in the sky had some synth effect, I am the walrus was very trippy indeed and I thought "yeah that could be it". Then comes set dose. The blaze on got very weird (and beautiful) at times, the meatstick had that very odd ambient jam. CK5 have everything the treatment as always. Anyways, I think that has something to do with it.
