As of 2022, which album by Keith Jarrett is said to be the best selling piano album in music history?

"The Köln Concert" is a live recording of solo piano improvisations performed by Keith Jarrett at the Opera House in Cologne in January 1975. The double-vinyl album was released in 1975 by ECM (Edition of Contemporary Music), an independent record label founded by Karl Egger, Manfred Eicher and Manfred Scheffner in Munich in 1969. The album has now become the best-selling solo album in jazz history and the best-selling piano album in music history, with sales of around 4 million.

Music critics and fans have said, "The popularity of "The Köln Concert" is in large measure thanks to its spiritual resonance, the idea of one man ascending to the stage to channel improvised, often repetitive mantra-like music in a communal setting." Additionally, it can't be stated too often that this concert was completely improvised except for the brief encore, which was based on an already-composed melody.
