From 1978-1982, Hancock recorded many albums consisting of jazz-inflected disco and pop music, beginning with Sunlight (featuring guest musicians like Tony Williams and Jaco Pastorius on the last track) (1978). Singing through a vocoder, he earned a British hit, "I Thought It Was You", although critics were unimpressed. [2]. This led to more vocoder on the 1979 follow-up, Feets, Don't Fail Me Now, which gave him another UK hit in "You Bet Your Love." Albums such as Monster (1980), Magic Windows (1981), and Lite Me Up (1982) were some of Hancock's most criticized and unwelcomed albums, the market at the time being somewhat saturated with similar pop-jazz hybrids from the likes of former bandmate Freddie Hubbard. Hancock himself had quite a limited role in some of those albums, leaving singing, composing and even producing to others. Mr. Hands (1980) is perhaps the one album during this period that was critically acclaimed. To the delight of many fans, there were no vocals on the album, and one track featured Jaco Pastorius on bass. The album contains a wide variety of different styles, including a disco instrumental song, a Latin-jazz number and an electronic piece in which Hancock plays alone with the help of computers.
