Very creative challenge, thankyou.
I remember Joni Mitchell talking about how she started as an artist, painting. And then wanted to apply art to music, and I think she ended up with such a unique and insteresting style that lasted the decades. And she was not hampered and mired by traditional music, but still respected the roots of great musicianship (lessons).
She had the best of both worlds, so I've always admired her so much.
Thank you for sharing that. I absolutely agree with your comments on Joni Mitchell. Every part of the music mattered in her creations; interesting composition, timeless lyrics, and killer musicianship.
