Is the “band” a group of any organisms? No.
Is the “band” a group of discrete objects? Yes.
Is the “band” a non-counted quantity of substance? No.
Is the “band” made out of rubber? No.
Is the “band” related to the event which the festival was held in commemoration of?
Would knowing what the event being commemorated was help?
Yes to both
Is the band an inanimate object?
Is it made out of :
- fabric/ cloth ?
- metal ?
- plastic ?
- elastic?
- paper?
Is the band a group of living beings?
No to all
Is the band a coloured stripe?
Is the band a broadcast wavelength?
Is the band a coloured stripe?
Is the band a broadcast wavelength?
No to all.
So, at some point there was an event which in some way involved a group of inanimate objects (which are not made of rubber, cloth, metal, plastic, elastic, or paper). After that, for a time in the late 20th century, there was a rock music festival in honor of this event, and because of the group of object’s relevance to the original event, the group of objects was brought to each of the festivals.
Is that correct so far?
More questions:
Are the objects made of matter?
Are the objects in the band all made of the same material?
Are the objects made, at least in part, from material of animal origin?
Are the objects made, at least in part, from material of plant origin?
Are the objects made, at least in part, from material of mineral origin?

Not exactly.
Was it a graphical element?
No.
As I understand it, we’re talking about a geological band–that is, a striation or some such of rock that’s at the site of the festival. Right? Like maybe a band of quartz made up of multiple types of quartz (thus a "rock group)?

OK, I got something wrong in my summary. Let’s see if we can figure out what.
Were the objects brought to the festival?
Do the objects naturally occur at the site of the festival?
I was thinking of the Stonehenge festival, but couldn’t link the word “band” to the stones there. Maybe the stones were from the same geological band or something. Close?
