'Sunlight' by Herbie Hancock is a 1978 jazz-funk, fusion album. It features Hancock's vocals through a vocoder as well as performances by drummer Tony Williams and bassist Jaco Pastorius. This was when Hancock began heading towards a more mainstream Smooth Jazz/R&B fusion. The album produced a hit-single entitled 'I Thought It Was You'. As a whole the album tends to lay more toward funk than a jazz record, and is reminiscent of much of the electro-funk of the time. This release marks the beginning of the 80s electro-era style that was more refined in Herbie's later albums such as 'Future Shock' and 'Sound-System'
