I caught my first glimpse (or I should say heard my first strain) of this recording in a somewhat serendipitous fashion: I had been searching through the then-mighty Napster for a good recording of the Bach G-minor Fugue, and was instantly struck by how great the violinist was in the file I managed to come upon. After some research, I discovered that it was Arthur Grumiaux, and I then wasted no time in getting the complete set of recordings.
Grumiaux's Bach is marvellous in sheer purity and vibrancy. He does not shy away from a contemporary rendition of these pieces, instead of encumbering himself with all-too-often artificial limitations of so called "performance practise". Instead, the violin literally rings like a bell when chords are played, while the line of the pieces is meticulously developed and maintained throughout (no mean feat, believe me).
It is hard to say which is the best recording of any piece, let alone something as frequently recorded as the Bach violin solo cycle, but this comes pretty darn close to such a title.
