I have David McGowans book Weird Scenes Inside the Canyon. IIRC, TEXOKIE compiled a huge amount of info on Laurel Canyon that we all discussed a couple of years ago. Very eye-opening.
One thing that bothered me at the time (I was in high school) was the fact that the music changed from being happy, carefree, and danceable to dark, depressing, and good for nothing but to sit around being sad.
I completely agree with you. It’s why, after a brief interest in Rock music, I found myself attracted more to the music of my parent’s generation - Big Band, The Great American Song Book, Sinatra, etc. The music that preceded the emergence of Rock had a positive energy. The ascendency of Rock, as it transitioned from Rock & Roll, was when the music embraced anger and despair and became a celebration of ugliness and noise. There are exceptions of course. But that was definitely the trend. After finding the anger of the music briefly appealing, as a young boy, I realized it was not appealing to my best instincts and I turned away from it.
