Bruno Mars, who has revived retro funk and R&B for a new generation, has completed a surprise sweep of the Grammys.

Mars won the night's top prize--Album of the Year--for his song "24K Magic". The Recording Academy, a body of 13,000 music professionals, also gave him Song of the Year for another track on the album -- "That's What I Like". This is the first time the funk revivalist has won the US industry's award for top song on his own. "24K Magic" is the title track of the Hawaiian-born singer's third album, which revives his mix of fun-loving retro funk but adds touches of 1980s-inspired synthesizers.
