Here's a great article that seems to describe, using only the violin, what I've found out about pretty much every instrument these days: the lack of originality of the current "top" instrumentalists.

Listen to Bach's sonatas and partitas for solo violin. Rachel Podger, Hilary Hahn, Rachel Barton Pine, Helene Schmitt. All these modern violinists sound different from one another.
Recently I heard a Bach violin partita on Harvard Radio and I decided to guess who that was. Even though I had not heard this particular partita from her, I decided that this was probably Rachel Podger. At the end, indeed, the announcer said it was her. She was recognizable.
No, this article is a hit job by a grumpy old man, who appears to lament a mythic 'golden age' of classical music. I find today's classical performers in general often unbelievable -- 'original' or not. So much talent, and great standard of playing.
Apart from solo violinists, there are also string quartets that sound unique. Have enjoyed the past few days Haydn's groundbreaking quartets op. 33 with the
Eybler Quartet. Incredible music making (on period instruments). Incisive, energetic phrasing yet with immaculate focus on flow at the same time. Passionate and thoughtful. The performances are just alive.

Agreed with other posters, Pat Kop is impressive.
