Many notable Mozart conductors have become broader in their tempos and more detail-obsessed as they aged. Walter, Beecham, Böhm, Klemperer, and even Sir Colin Davis have all fallen under the spell of the music's perfection to the point where they could hardly bear to let it alone. On the other side of the equation are equally great conductors such as Szell, Reiner, Casals, and Toscanini, whose vision intensified instead of mellowing. It is to the latter group that Menuhin belongs, and these superb performances call to mind Toscanini at his best, in the tensile strength of the melodic line, subtle rubato, and miraculously clear articulation.
Karl Böhm's recording of the Mozart symphonies with the Berlin Philharmonic Orchestra is among the most respected and beloved sets of this important body of work. Böhm's set was the first complete recording of the symphonies (including several that subsequent scholarship has shown to be written by other composers and misattributed to Mozart) and it remains a substantial achievement because of the conductor's stature as a Mozartian and because of the enthusiastic and refined playing of the Berlin Philharmonic.
Karl August Leopold Böhm (1894 – 1981) was an Austrian conductor. (…) Böhm was praised for his rhythmically robust interpretations of the operas and symphonies of Mozart, and in the 1960s he was entrusted with recording all the Mozart symphonies with the Berlin Philharmonic. His brisk, straightforward way with Wagner won adherents, as did his readings of the symphonies of Brahms, Bruckner and Schubert. His 1971 complete recording of the Beethoven symphonies with the Vienna Philharmonic was also highly regarded. On a less common front, he championed and recorded Alban Berg's avant-garde operas Wozzeck and Lulu before they gained a foothold in the standard repertory. Böhm mentioned in the notes to his recordings of these works that he and Berg discussed the orchestrations, leading to changes in the score (as he had similarly done, previously, with Richard Strauss). He received numerous honors, among them first Austrian Generalmusikdirektor in 1964.
