I have seen both of these videos dozens of times, I LOVE JANIS! JANIS JOPLIN really knew how to sing her songs with powerful passion and emotion. Janis gave it all to you, she held nothing back.
Absolutely, I don't think there's a single performance where you see her holding back. It's definitely something to admire in a singer, it had to be exhausting!
The 60's music speaks for itself, give it time, I bet that many of your friends will eventually open their minds and listen to 60's music. Doing this, they will realize that the 60's music was the greatest decade (1960's) for Rock n' Roll.
Yeah, not everything can happen in a heartbeat, after all. They're learning about a lot of 60's and 70's music at school now, hopefully that will make some of them see how good the music actually is
