You should listen to Hilary Hahn's renditions of Bach's partitas and sonatas. She brings out the subtleties of Bach's composing beautifully, and the purity of his music is easy to appreciate in these solo pieces.
Don't think so. Her recordings of his violin concerts on the other hand are able to clearly show his genius due to the more complex orchestration and interplay between the different instruments.
I mean, I enjoy them too. Good mention. I had a feeling the parent wasn't a fan of the baroque counterpoint, and the violin concertos feature more of that.
