The Köln Concert is a live album consisting of piano improvisation by Keith Jarrett. The album was recorded at the Opera House in Cologne, Germany, on January 24, 1975. The double-vinyl live album was released in November of the same year.
The most remarkable part about this live album is that it was a one-person show. Jarrett was running on little sleep and felt pain on the night the album was recorded. He also didn’t receive the piano he requested. Yet, despite all of this he created one of the bestselling solo jazz and piano albums in the genre’s history.
