Sonya Kitchell with Joni standing in front of her painting of Coco.

According to Sonya:
The photos with Joni Mitchell were taken at a live taping for Yahoo Music with Herbie Hancock. The painting behind us, of her dog Coco, was done there. Each artist who's performed on the series is given a tablet to sign or make art upon, and this is what Joni did.

Many thanks to Sonya Kitchell for permission to display her photo.
