The fingers are flying and the notes are impeccably in place. The melody is clearly Vivaldi.
But what's this throaty growl of an amped-up electric guitar?
Just a YouTube performance by Tina S. of the Presto section of "Summer," a part of Vivaldi's ever popular "Four Seasons."
The video was uploaded by Tina, and it explains the 14-year-old student calls it her "Vivaldi Tribute."
She plays on her Vigier Excalibur under the supervision of teacher Renaud Louis-Servais.
"This version is an extract from Patrick Rondat's guitar adaptation in his 'Amphibia' album (1996)," it explains.
It wasn't like this originally. Composed by Antonio Vivaldi in 1723, the baroque period example was published in 1725 as part of a set of 12 concerti.
The original arrangement was for solo violin with string quartet and basso continuo, and was written to represent the four seasons. Pizzicato notes fill "Winter," while "Summer" evokes a thunderstorm in its final movement.
