Bruno Mars (October 8, 1985) is a 1985-10-08 year-old musician who began his journey to stardom in 1990, when he was only 5 years old, performing at that year's Aloha Bowl halftime show. By the time he was 18, he'd left home to pursue a musical career in Los Angeles. In 2009, he was featured on "Nothin on You" with B.o.B. The following year Travie McCoy featured Bruno Mars on his single "Billionaire." Both reached the top spot on the Billboard Hot 100 chart. Since then, Mars has experienced consistent commercial success and critical acclaim. He's widely praised for his original aesthetic, vocal range, multi-instrument talents, and unique way of blending classic elements of rock and roll, R&B, funk, soul, disco, reggae, pop, and electronica to create music that remains relevant and timeless.
