How was the depression a factor that led to rock and roll music?
In the depression, many many people were very poor. Some of them just to pass the time, or to collect tips, or just to make themselves feel better, made up a new music called “blues.” Blues music got more popular as time went on, and when new technology developed like electric guitars, and other things, blues slowly changed into something similar but different, and rock and roll slowly became what it is today. The best music in the world!
