Adolf Busch, the Busch Quartet, son-in-law Rudolf Serkin (if I said brother-in-law in the video, my bad), and associated musicians represented the acme of musical excellence in the 1930s and 40s, especially in Beethoven, Brahms and Schubert. Warner has--for the moment--made it possible for us to hear 16 CDs worth of their legendary recordings in a single convenient box. This is self-recommending.
