Who is Polina Tarasenko?

Videos of Ms. T playing her trombone show up regularly in my Facebook feed. Who is she?

She seems to be quite a talented player. Just another kid who can kick my butt on the horn.

It just goes to show, on any known instrument, there's an 8 year old on youtube playing better than we'll ever be.

Check out her as a 10 year old playing All of Me on a trombone bigger than her that falls apart halfway:

Here's a better answer.

I enjoy listening to this 2023 performance of Joseph Guy Ropartz Piece in E-flat Minor.
First heard of her playing on the ITF 2019 Daft Punk Harder, Better, Faster, Stronger project.

To my ears there is a lovely warm tone and a patient vibrato across her recordings.

She is Ukrainian musician (not only trombone player).
In 2018 she finished Gnessin Moscow Special School of Music, it is "special" school where children study "normal" program (math, biology, history etc.) and "music" disciplines (main instrument, piano, solfeggio, music theory etc.).
Usually, after such education graduates enter the conservatory or Institute of Music.
After graduation she studied in Germany and Switzerland.
AFAIK now she lives in Europe.
