That has never actually occurred to me, though you are right of course. I've always thought of a successful audition displaying the most varied repertoire of piece, though now I realize that this desirable variety can be found in the tone of a player as well. Listening to a player like Pahud or Gallois (on some recordings more than others) playing a piece like the Sarabande, I often sense a sort of richness of tone and vibrato that makes a performance much more interesting. When I think about it, I guess that I'm more impressed by these performances that make sparseness of notes seem interesting than the ones that are simply fast displays of notes.

Anyway, regarding a recording of it, I would suggest purchasing a good recording by Galway, Pahud, Rampal, or another one of the greats (I also like the Joshua Smith recording a lot). If you can't do that, you might check out Rampal's recording on youtube: http://www.youtube.com/watch?v=eZagzLnzrDI
