Rick Astley sings inside a swirling Starry Night sky

Recreate Rick Astley’s unmistakable dance as an HTML animation about one minute long, made from bold, moving brushstrokes and synced to music. His coat, microphone, and shadows should swing with exaggerated rhythm. Make it a piece of art: artistic, beautiful, polished and incredibly fun and approximately 1m long. Draw everything in code, including the music; no external media or website UI.
