The Köln Concert

The Köln Concert is a concert recording by the pianist Keith Jarrett of solo piano improvisations performed at the Opera House in Cologne (German: Köln) on January 24, 1975. The double-vinyl album was released in the autumn of 1975 by the ECM Records label to critical acclaim, and went on to become the best-selling solo album in jazz history, and the all-time best-selling piano album, with sales of more than 3.5 million.

The Köln concert

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. ECM Records producer Manfred Eicher later said: "Probably [Jarrett] played it the way he did because it was not a good piano. Because he could not fall in love with the sound of it, he found another way to get the most out of it."
