For "Occupation", Kelvin abandons the typical Cantonese pop style and combines hard rock with rap. The stye is very Linkin Park like, a refreshing sound for both Kelvin as well as the Hong Kong music industry. Instead of singing about love, he takes on more political and societal themes by singing about last year's Occupy Wall Street and government's control over society.
While his voice is very fitting for slow and love songs, I'm glad Kelvin is going beyond that and experimenting with different musical styles. "Occupation" is a fantastic song that reflects a theme and level of intensity not usually seen in mainstream Cantonese music. Kelvin may have started off as the typical Cantopop singer, but has greatly matured and with this song along with his recent material, he's setting himself apart and proving to be one of the brightest and most refreshing young singers in Hong Kong today.
