Carnegie Hall, New York, New York (09/26/2005). Keith Jarrett never ceases to amaze, and amaze he does on the two-disc CARNEGIE HALL CONCERT. He's known for solo piano concerts of completely improvised music that set a high standard for invention, elegance, and sheer compositional ingenuity, but it's almost incomprehensible that Jarrett is able not only to sustain these qualities, but to push them toward greater heights on each outing. The pieces on CARNEGIE HALL CONCERT are markedly different from Jarrett's previous work: dense, internal, and noticeably compressed, yet without being shorn of the artist's trademark sense of lyricism, classical nuance, or bluesy groove. Jarrett continues to grow as a master of his instrument and the world of musical ideas, and the results are spectacular to behold.
