Keith Jarrett "Sun Bear Concerts" disc 4,
TokyoThese reviews from the wiki page I think accurately describe these concerts captured on six discs:
The AllMusic review by Richard S. Ginell states, "While Sun Bear breaks little ground that his earlier solo piano albums had not already covered, it is nevertheless richly inventive within Jarrett's personal parameter of idioms. If price is not a barrier, the Jarrett devotee need not hesitate".
A review by Thom Jurek of the 2021 facsimile edition refers to the album as "a pinnacle of creative invention in Jarrett's voluminous catalog".
Writing for Rolling Stone, Mikal Gilmore remarked, "Nowhere else in his collected works does music seem more effortless and splendid. From the opening phrase onward, it unfolds like an idyllic dream on the border of consciousness, and like the best of dreams – or narratives – you never want it to end. It is, to my mind, one of the few real self-contained epics in Seventies music."
Writing for ECM blog Between Sound and Space, Tyran Grillo commented, "The Sun Bear Concerts prove that not only is Jarrett an unparalleled improviser but a melodician of the highest order. These pieces are consistent in their striking differences, yet all seem couched in a palpable melancholy that is striated with joy. Despite the sheer volume of music that seems to reside in Jarrett's entire physiological being, one gets the sense after listening to these six-and-a-half hours of brilliance that they comprise but a single molecule of creation dissected and slowed to discernible speeds. At least we, at this moment in time, can witness these atomic paths, knowing full well that their beauty lies in an allegiance to silence. Not a single note ever feels out of place, because it has no place to begin with, except as the emblem of that which is gone before it arrives... If you ever buy only one recording of Keith Jarrett, look no further. Then again, why stop here?"
Jarrett biographer Ian Carr called Sun Bear Concerts "a monumental record of Jarrett's work at a crucial stage of his development," and wrote: "there are amazingly few dead or dull patches and all five concerts seem related like a massive suite. The improvisation also seems much more organic than on the earlier live solo albums... There are more new colours and new rhythms... and the music tends to evolve rather than to chop and change. There is a clear sense of ebbing and flowing, and the marvellous dynamics, ranging from triple forte to pianissimo, also enhance this."
