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 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 Keith Jarrett Standards Trio gets back down to business with two CDs' worth of familiar and perhaps not-so-familiar tunes, recorded in one evening in Cologne, Germany. There is a concept this time, for all the standards carry a dedication to some jazz man or woman who performed them – and they are not predictable choices; Lee Konitz for "Lover Man," "It's Easy to Remember" for John Coltrane, "All of You" for Miles Davis, etc. Almost every number has a reflective solo piano introduction, with one of the notable exceptions being Jarrett's rolling, convoluted opening variations on "All the Things You Are" (Sonny Rollins). "Solar" (the Bill Evans tribute) has challenging, fractured interplay between Jarrett, Jack DeJohnette and Gary Peacock, and it directly segues into Jarrett's own obsessive "Sun Prayer," which seems to lose its way after a fine start.
