The fourth of Keith Jarrett's solo piano albums turns inward, away from the funky, pulsating melodic inventions of its predecessors toward a more reflective, scattered, never-despairing romanticism well removed from the pulse of jazz. As such, it is paradoxically his weakest solo piano album of the '70s and also the most influential, for here is the blueprint for sensitive meandering that the New Age piano crowd took off upon in the 1980s. A studio session, Staircase is actually only one of four separately titled improvisations on this double album (now on one CD) -- the others are "Hourglass," "Sundial" and "Sand" -- but their overall moods of repose are so similar that it hardly matters what they are called. One can always admire Jarrett's lovely tone and flexible touch, yet when he gets stuck for ideas, the repetitions finally begin to grate. Maybe he really needs the stimulus of a live audience in order to get the creative and rhythmic juices flowing when flying solo.
