Recorded in 1969, in Basel. I have just added the English subtitles, don't forget to turn them on. In this rare footage Argerich warms up, plays a few bars of Beethoven's Sonata Op. 101 and performs the Chopin Mazurka in C major, Op. 24 No. 2.
Please, don't download and repost this video somewhere else.
There is a complete performance of the Beethoven Sonata on my channel (audio only). Check it here: https://youtu.be/yej-5f67Z7Y
