How about "Hard Country"?
As we've all heard, the All Fired Up studio version
(https://www.youtube.com/watch?v=eF0LeaH44Yg),
as well as the current live version, of this Jack Sundrud classic initiates with an opening acoustic guitar, and slowly/methodically adds mandolin, keyboards, bass, drums, and a soaring electric slide guitar.
This song brilliantly symbolizes societal evolution from pastoral, simple existence into fast-paced, technology-centered, complicated life.
