(1) #Phish Sphere Theme guess

N1: Lithosphere - The rigid outer part of the earth

N2: Hydrosphere - all the water on earths surface (including car wash water and dog tongue bath saliva)

N3: Planisphere - a map formed by the projection of a sphere or part of a sphere on a plane, especially an adjustable circular star map that shows the appearance of the heavens at a specific time and place.

(2) planisphere is just a fancy name for a map of the stars. Also found on the Temple of Denderah. Used to track time. That Temple looks a little familiar..

Time is a thread running through the individual sphere themes.

So what’s left for N4? What happens over the flowing waters of time and space, on the earth where we face mortality, life and death? We Evolve.

A planisphere set could look like this:

Set1: Corona, Tube, Martian Monster, Spock’s Brain, Mule, BBFCFM, Mercury, Moonage Daydream

Set2: Halley’s Comet>Soul Planet>Sea of Stars, 2001, Pebble & Marbles

E: Sanity, SANTOS

If you look at two songs over the first two nights that have pivotal spots in the second sets, a focus on time seems clear..

N1: Mike’s Song “trapped in time” with a slow moving set visual with a device that had the machinations of a clock.

N2: WTU, the only song other than Hood and YEM* not mentioning water. But the lyrics for the song certainly reference aspects of time.

*def hints at evolution Boy, Man, God, and visually referenced water.

@spreaditround I'm with you on lithosphere and hydrosphere, but then suspect biosphere (including evolution) and atmosphere (liberally extending to space) to round it out
