Unorthodox Jukebox is the second studio album by American singer-songwriter Bruno Mars, released on December 7, 2012, by Atlantic Records. It follows his successful debut album, Doo-Wops & Hooligans (2010). Mars took influence from several different kinds of music and wanted to create an album that was more 'real' than his previous one. As a result, Unorthodox Jukebox presents a wide range of styles such as reggae rock, disco, and soul music.
The album was a huge commercial success, peaking at number one on the Billboard 200 in the US, making it Mars' first number one album in the country. It also topped the charts in numerous countries including Australia, Canada, Switzerland, and the UK. The album was nominated for Best Pop Vocal Album at the 56th Annual Grammy Awards.
It spawned five singles and was further promoted with The Moonshine Jungle Tour in 2013-2014. Notable tracks include "Locked Out of Heaven," "When I Was Your Man," and "Treasure," all of which became international hits. The album was generally well-received by music critics, who praised Mars' versatility and noted his improvement from his debut album.
Overall, Unorthodox Jukebox underscored Mars' unique artistic range and reinforced his reputation as a formidable talent in the music industry.
