International ArtistAfter working a string of behind-the-scenes jobs – including writing songs for Brandy, singing backup for the Sugababes, and impersonating Elvis – songwriter/producer Bruno Mars put his name on top of the charts in 2009 by co-writing Flo Rida’s hit song Right Round. One year later, he collaborated with rapper B.o.B on NothinĂª on You, and co-wrote Travie McCoy’s Billionaire, both of which became Top Ten hits. Bruno Mars used that momentum to launch a solo career, quickly becoming the first male vocalist in two decades to crack the Top Ten with his first four singles. Bruno Mars continues to dominate the international charts with a long list of hits: Just the Way You Are, Grenade, Locked out of Heaven and Uptown Funk.
