BBC Radio 4 has produced a programme about Keith Jarrett's landmark recording. From their description:

"Fifty years after Keith Jarrett performed the Koln Concert to a sellout crowd, Kevin le Gendre explores the enduring appeal of the biggest selling solo piano record of all time, and unpicks a new musical language born out of adversity."

The 28-minute programme features Jacob Collier, Geoff Dyer, Nikki Yeoh, Django Bates, and Maki Namekawa. It was broadcast on January 14, 2025 and will be available for over a year on the BBC Radio 4 website.
