Watch a 90-year-old husband and wife play Bach together in a beautiful video

They've been married for over 65 years: when this couple sit at the piano, something magical happens.

György and Márta Kurtág Bach duet

Composer and pianist György Kurtág is one of the most important figures in music from the past 100 years. He has also played with his wife, Márta, another very accomplished pianist, for many years. Recent footage taken from a live concert in Budapest reveals the depth of their musical understanding.

The couple play transcriptions made by the composer of Bach's choral prelude Das alte Jahr vergangen ist BWV 614, his Duet BWV 804 and a movement from the Baroque composer's cantata Actus tragicus.

György was born in Romania in 1926, moved to Hungary in 1946 and married pianist Márta Kinsker in 1947. The two have duetted ever since.  

This is what it sounds like when you live and play Bach together for 70 years:
