Lovely story in this new TED talk by (Firestarters speaker) Tim Harford focusing on how constraints contribute to creativity, and concerning Keith Jarrett's 1975 performance at the opera house in Cologne - one of the most famous piano recordings of all time. Worth listening to Tim tell the story in his usual compelling way, but here's the essence of it taken from the Wikipedia entry:
'The concert was organized by 17-year-old Vera Brandes, then Germany’s youngest concert promoter. At Jarrett's request, Brandes had selected a Bösendorfer 290 Imperial concert grand piano for the performance. However, there was some confusion by the opera house staff and instead they found another Bösendorfer piano backstage – a much smaller baby grand – and, assuming it was the one requested, placed it on the stage. Unfortunately, the error was discovered too late for the correct Bösendorfer to be delivered to the venue in time for the evening's concert. The piano they had was intended for rehearsals only and was in poor condition and required several hours of tuning and adjusting to make it playable. The instrument was tinny and thin in the upper registers and weak in the bass register, and the pedals did not work properly. Consequently, Jarrett often used ostinatos and rolling left-hand rhythmic figures during his Köln performance to give the effect of stronger bass notes, and concentrated his playing in the middle portion of the keyboard.
Jarrett arrived at the opera house late in the afternoon and tired after an exhausting long drive from Zürich, Switzerland, where he had performed a few days earlier. He had not slept well in several nights and was in pain from back problems and had to wear a brace. After trying out the substandard piano and learning a replacement instrument was not available, Jarrett nearly refused to play and Brandes had to convince him to perform as the concert was scheduled to begin in just a few hours.'
The double-vinyl album was released to critical acclaim, and became the best-selling solo album in jazz history, and the all-time best-selling piano album.
