Review of Antonella Martinelli from ‘An Italian Straw Hat.’
“One dancer who I was quite smitten over danced and silent acted with such ebullience I noticed her all the way from the corps de ballet. The apple of my eye radiated a Snow White/Betty Boop/Charleston Girl kind of beauty. Perhaps she was a new dancer recently hired from another company, a call up from the National Ballet School, or contracted to fill out casting. Sadly, I have no idea who this beauty is? I cannot critique her ballet dancing as her role just called for watching the story unfold on stage and do some waltzing. She was often paired with Alejandra Perez-Gomez. Kudos to the mystery brunette for always staying in character and so obviously enjoying her time on stage.”
