The Köln Concert is one of the most legendary recordings in jazz history – the best-selling solo jazz album ever made. Yet the performance behind it almost didn’t happen.

This fascinating documentary retraces Keith Jarrett’s famous 1975 concert in Cologne Germany, where a series of unexpected obstacles – including a problematic piano and an exhausted musician – nearly caused the event to collapse. Through an investigation into the mysterious instrument and the fragmented memories of those involved, the film explores how a concert expected to be disastrous became an iconic recording. Blending storytelling and inquiry, it reveals how chance, limitation and improvisation can spark moments of extraordinary artistic creation.
