What a tragic loss to the entire music community.
I think everyone has a special connection to "the music of your youth", your teen years... The music speaks to all of your emotions as well as what is going on in our society as a whole during those formative years. If you are a really talented musician, your music transcends through later generations. David Crosby definitely did that.
I've listened to a lot of music today and CSN & Y was featured in much of it, back to Woodstock. I had forgotten how much his early music reminds me of Jerry Garcia and the Dead. It's a sad day.
RIP
