Herbie Hancock is a true icon of modern music. Throughout his explorations, he has transcended limitations and genres while maintaining his unmistakable voice. With an illustrious career spanning five decades and 14 Grammy Awards, he continues to amaze audiences across the globe. There are few artists in the music industry who have had more influence on acoustic and electronic jazz and R&B than Herbie Hancock. As Miles Davis said in his autobiography, "Herbie was the step after Bud Powell and Thelonious Monk, and I haven't heard anybody yet who has come after him."

Herbie Hancock's Warner Brothers recordings represent the emergence and unfolding of his Mwandishi Band. This genre-crossing group pioneered an expressive use of sound and technologies, a blend of beat and abstraction, Afrocentric sensibilities, and while fronted by a strong leader, a collectivist approach to making music. The band prepared the groundwork for Hancock's emergence as a proponent of a synergy between jazz and funk. The Warner Bros. Years (1969-1972) brings together his complete catalogue for the label, together with singles and promotional recordings, reissued for the very first time.

Packaged in a clamshell box, each album is packaged in a mini-LP CD cardboard replica of the original sleeve with original artwork. Accompanying the discs is a 32-page booklet, featuring a comprehensive essay by Bob Gluck, author of You'll Know When You Get There: Herbie Hancock And The Mwandishi Band. Each disc comes with the original albums, together with singles and promo edits reissued for the very first time
