You might consider some of the recordings by both Joshua Bell, whom you correctly named as the violinist on the soundtrack, or the violinist Arturo Delmoni. Both play with an emotion and passion that consistently do justice to the music they've selected.
Of Arturo Delmoni's recordings, I highly recommend the following:
"Ysaye, Kreisler, Bach: Solo Violin Works"
"Songs My Mother Taught Me" with piano accompanist Meg Vas..
"Music for a Glass Bead Game" with cellist Nathaniel Rosen, alternating the music of Bach and Kodaly
Enjoy your explorations!
