The things you did when you were young are often extremely embarrassing as you get older. The old joke used to be about people's high school yearbook photos, and a cursory search on the Internet will show you the embarrassing evidence of these when it comes to famous celebrities. Nowadays, you can find evidence of every period of a person's development thanks to social media.
We'll also be seeing the embarrassing, earliest recordings of bands floating around becoming a more frequent occurrence, as our new rock stars will be able to put out everything they do on Bandcamp from their beginning to their masterpiece. Back in the day, you had to search for long out-of-print first albums to hear those sorts of things.
They did exist, though, whenever bands or musicians managed to get a recording contract long before they were ready for prime time. Those records are the stuff of legend now, but thanks to the Internet and intrepid fans, we're able to look back and have a laugh.
