If you think the 2020s have been wild, check out the 1970s: a deadly war divided the nation, civil rights were fresh in everyone's minds, and disco was taking the country by storm.

Along with portable music, music festivals took off in the 70s. Prior to Woodstock, festivals were a tamer affair, but ideals of freedom, love, and peace were spreading like wildfire through the hippie movement, which championed the art and expression of music.

Additionally, you might not even have had access to a bank, depending on who you were.
