For his third Blue Note album Inventions & Dimensions (1963), pianist Herbie Hancock began moving away from the modernist hard bop sound that defined his first two albums Takin' Off and My Point Of View. Inspired by explorers like Eric Dolphy and Tony Williams, Hancock went in search of greater musical freedom by composing a set of ingenious originals each with their own unique inner logic that did away with what he considered the established jazz "assumptions" of the time.
