OK. Since nobody else said it.
I don't normally like to dis musicians of any kind, but....
What a bunch of tools.
And for the theory guys....
Which Box were they playing with?
Do they all have the same Key?
Not sure about the scale, but probably metricorian dominant?
A lot of parallel motion with next to no voice leading.
But the dynamics were good.
For the gear guys....
Do all the boxes have the same tonal quality?
Do different metals have different qualities?
Does size matter?
Does the brand name make a difference?
They definitely didn't need amps, but what if they go on to play stadiums?
Were they getting corporate sponsorship from a box company or a brewery?
Was "The Lonely Island" involved?
And I'm only kidding.
That was pretty cool with some what I assume was some relatively heavy metal.
And they even hooked them up to power cords.
I almost forgot to mention how they were banging the wrenches.
