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.

This is the Keith Jarrett Trio's – featuring bassist Gary Peacock and drummer Jack DeJohnette – elegy for their former employer Miles Davis, recorded only 13 days after the maestro's death. The lonely figure in shadow with a horn on the cover contrasts with the joyous spirit of many of the tracks on this CD, yet there is still a ghostly presence to deal with – and in keeping with Miles' credo, Jarrett's choice of notes is often more purposefully spare than usual. There is symmetry in the organization of the album, with "Bye Bye Blackbird" opening and the trio's equally jaunty "Blackbird, Bye Bye" closing the album, and the interior tracks immediately following the former and preceding the latter are "You Won't Forget Me" and "I Thought About You." The centerpiece of the CD is an 18-and-a-half-minute group improvisation, "For Miles," which after some DeJohnette tumbling around becomes a dirge sometimes reminiscent of Miles' own elegy for Duke Ellington, "He Loved Him Madly." As an immediate response to a traumatic event, Jarrett and his colleagues strike the right emotional balance to create one of their more meaningful albums.

One of the best recordings for Keith Jarrett's mid-'70s American quartet (whose style differed sharply from its European doppelgänger), The Survivors' Suite opens with Jarrett's aching, breathy sigh on the bass recorder, evoking the sound of a horn somewhere across a great expanse of fog. Percussion soon punctuates the melodic line to give the opening a more spiritual, ritualistic feel, which is only the first of many mutations that this album will go through. Divided into two parts, entitled "Beginning" and "Conclusion," this suite effortlessly flows between its movements which range from fiery free jazz to open, meditative atmospheric pieces showing heavy input from indigenous musics to instrumental solos that owe a sylistic debt to the music of the previous decade.
