While I am not a fan of jazz, this illustration, done from a model in real time, real life, is inspired by electrifying singers whose voices are instruments themselves. They are the jazz.
The opera singer in Diva. Amy Winehouse, Annie Lennox, Grace Jones, Vanessa Daou, Lene Lovich, Mary Jane Coles, Nina Hagen, Nina Simone, Tina Turner...etc. I am often smitten by these magical beings.
