Szeryng made two complete cycles of the Bach sonatas andpartitas: one in 1954 for Columbia records, and the one currentlydiscussed in 1968. The 1954 recording is a slightly better performance. I have the old Odyssey LP copy of the 1954 recording, and am seeking the quickly-out-of-print Sony CD version of the 1954 recording. Having said this, the DG CD version here offered is a marvelous recording, and cheap to boot. You won't regret this purchase. When Artur Rubinstein first heard Szeryng play Bach, he was reduced to tears and begged to become Szeryng's accompanist.
