Bach's solo cello works have had many fine and even legendary performances by the likes of Casals, Rostropovich, Bylsma, Starker, Gendron, Fournier, Wispelwey, Iserelis and others. How to chose?
Here's a simple recommendation to the newer collector or listener - don't stress out over trying to find "the best" recording or the performer who best "taps into the soul intent of Bach" or whatever. Listen to the sound bites of Alexander Rudin's readings hereand see if it speaks to you, then get it and merely listen and marvel at Bach's timeless compositions and imposing musical talents.
As others note, these are very well performed pieces that well exude the spirit of Bach's intent played with great skill and well recorded. Sometimes one can over-focus on the finding he "Holy Grail" recording that the deeper message of the music is passed right by.
Just because its Naxos at budget price does not mean inferior. This is one of those above-average value recordings that one should grab. The recorded sound is full and deep, bringing our the nuances of Rudin's cello and Bach's brillance. Compositions - 5 stars; Performance - 5 stars; Recording - 4.5 stars.
