Dedication is the sixteenth album by Herbie Hancock. It was recorded in Japan in 1974 while Hancock was touring and first released on the Japanese CBS Sony label in September 21, 1974. Hancock performs "Maiden Voyage" and "Dolphin Dance" acoustically, while "Nobu" and "Cantaloupe Island" were performed on electric keyboards. It wasn't released in CD outside Japan until 2013, as part of the "Herbie Hancock the complete Columbia album collection 1972-1988" box set.The track "Nobu" is regarded by many (including As One) as the first ever techno track, due to its other-worldly repetitive electronic groove.
