Leo's got a point, and I realize that Disco has a lot in common with Autism.
Let's take a look:
2)Sometimes the vocals are inaudible.
3)It certainly gets us moving.
4)Was very popular in the 70's but no one admitted it.
5)Had environmental triggers like drugs,alcohol,free love, and aerosol cans galore (to clarify I'm only talking about disco here)
6)Stereotypical 70's clothes are very sensory friendly - that polyester is quite soft and non-restrictive.
7)Bright lights and colors were popular off and on the dance floor (sensory seekers only please)
Did I miss any? Little help, little help?
