There was an idea to treat outer space like the ocean it is and in 1977 they launched spaceships Voyager 1 & 2 replete with messages in a bottle ostensibly for aliens to discover and consider.
No paintings, no sculpture, no architecture and no modern dance. What did they include to impress the aliens if either Voyager was successful?
Azerbaijani folk music,
Blind Willie Johnson,
Valya Balkanska and
recordings of people saying hello in 55 different languages.
Music is our species way of showing off intelligence.
