For his third album, Inventions and Dimensions, Herbie Hancock changed course dramatically. Instead of recording another multifaceted album like My Point of View, he explored a Latin-inflected variation of post-bop with a small quartet. Hancock is the main harmonic focus of the music - his three colleagues are bassist Paul Chambers, drummer Willie Bobo, and percussionist Osvaldo "Chihuahua" Martinez, who plays conga and bongo. Hancock has created an improvisational atmosphere where the rhythms are fluid and the chords, harmonies, and melodies are unexpected. On every song but one, the melodies and chords were improvised, with Hancock's harmonic ideas arising from the rhythms during the recording. The result is risky, unpredictable music that is intensely cerebral and quite satisfying. Inventions and Dimensions displays his willingness to experiment and illustrates that his playing is reaching new, idiosyncratic heights. (allmusic) Numbered first press of 500 copies.
