The recent superb Beethoven violin concerto recordings by Patricia Kopatchinskaja, Christian Tetzlaff and Liza Ferschtman were spoiled for me by their bizarre choice of cadenzas (when so many good alternatives exist). It would not have taken much to put the cadenzas on a separate track and thus give us the option of inserting some other version. That (should be) an advantage of the digital age. There are many good cadenzas for both the Beethoven and the Brahms violin concertos, and any decent violinist should have 2-3 in his or her repertoire. Give us a choice, and avoid having excellent performances spoiled by bizarre cadenzas. After Brahms, pretty well all composers became wise and wrote their own cadenzas (or supervised the contribution of some virtuoso). Ruggiero Ricci produced CDs of both the Beethoven and Brahms concertos with a wide selection of alternative cadenzas; so it can be done.
