All we know is that her name is Tina, she is French and she knows how to shred. In this video she plays a bit of Vivaldi by way of Patrick Rondat.

"Presto" is the 3d movement from Antonio Vivaldi's "Summer", from the "Four Seasons". This version is an extract from Patrick Rondat's guitar adaptation in his "Amphibia" album - Tina S on Youtube

Wolfgang Van Halen likes her too.
