Bruno Mars, "Unorthodox Jukebox"

About this Article

Bruno Mars likes to mix it up. Almost every song on his second album dabbles in a different genre. The 27-year-old singer-songwriter-producer shows growing sophistication, musically and lyrically, on "Unorthodox Jukebox," a retro-pop collection of 10 tracks with elements of rock, funk, country and reggae. There's even a heartbreaking piano ballad.
