Empyrean Isles is the fourth album by American jazz pianist Herbie Hancock, recorded on June 17, 1964 for Blue Note Records. It features the debut of two of his most popular compositions, "One Finger Snap" and "Cantaloupe Island". From the 1999 reissue liner notes by Bob Blumenthal: "If someone had ordered up a program that explored four distinct areas of jazz expression with equal brilliance, they could not have done better than Empyrean Isles. It is as if Hancock had set out to present 'changes,' modal, funk and free playing and delivered each at its apex."
