A wonderful documentary film featuring Arthur Rubinstein which shows
him improvising a lot and playing snippets from the following works:
Chopin: Etude in A-Flat Major, Op. 25 No. 1;
" Etude in C Major, Op. 10 No. 1;
" Etude in A minor, Op. 10 No. 2;
" Ballade No. 1 in G minor, Op. 23;
Szymanowsky: Symphonie Concertante, Op. 60;
Ravel: Valses nobles et sentimentales;
Schubert: Sonata in B-Flat Major, D. 960.
The spoken parts are all in the original German, and the English
subtitles -- just hit the "CC" button in the playback window to show
the subtitles (or to turn them off if you prefer).
This clip was made in 1966 by the North German Radio when Arthur
Rubinstein came to Hamburg, Germany to inspect his own favorite,
personal Hamburg Steinway D-274 piano which was dropped from a crane
somewhere while he was taking it on tour. It was sent back to the
Hamburg Steinway factory for repairs. The event takes place in a room
at the Steinway factory in Stellingen, a suburb of Hamburg.
