After a period of ceaseless ubiquity that saw him climb to the top of the Billboard Hot 100, collaborate with every rapper on the planet, and perform at seemingly every awards show known to man, Bruno Mars stepped out of the spotlight for a little while to work on his second album. The dude is finally back with a new album called Unorthodox Jukebox, and he just dropped its first single “Locked Out of Heaven.”

“Locked Out of Heaven” continues Mars’ “What if Stevie Wonder traveled to the future?” approach, melding together various eras of R&B, rock, and funk like second nature. The melody isn’t as immediate as some of his past hits, but it does have a gloriously chest-pounding bridge that should sound good next to “It Will Rain” during Bruno’s shows.

Give “Locked Out of Heaven” a listen below.

If you heard that main riff and expected Kat Dennings to suddenly start bantering with diner patrons, you’re not alone, as it has the same vibe as Peter, Bjorn, and John’s “Second Chance.”

Today brought a lot of big news for Mars, as it was announced he will also serve as both the host and musical guest on the October 20 episode of Saturday Night Live. He joins double-threat luminaries like Taylor Swift, Britney Spears, Mick Jagger, Jennifer Lopez, Justin Timberlake, and Garth Brooks.

Unorthodox Jukebox will hit stores on December 11, just in time to stuff the stockings.

What do you think of “Locked Out of Heaven”? Is it a good choice for a first single? How does it stack up to Mars’ other hits? Leave your reactions in the comments.
