Over the weekend, this video was floating on the Internet. In the UK, Bruno Mars dropped by BBC Radio to promote his music off his Doo-Wops & Hooligans album. One of the songs he sang was Katy Perry’s California Gurls. It’s not the some pop version you hear on the radio, he slows it down to give the song a R&B and jazz feel. The live performance is chill and laid back much his Billboard Tastemaker session. Check out Bruno Mars unplugged.
