American singer, producer and multi-instrumentalist Bruno Mars is known for his massive worldwide appeal, performing in a variety of musical styles, including R&B, funk, pop and soul. Still only 31 years old, and basically at the peak of his career, Mars has already been nominated for dozens of Grammy awards, winning 5, and become one of the best-selling artists of all time. His single “Uptown Funk” was number 1 on the Billboard “Hot 100” longer than any other song in history, and he had 5 songs hit number 1 on those charts fastest than any other artist since Elvis Presley. Bruno Mars performed at the Super Bowl halftime show in 2014, so he knows a thing or two about huge arena gigs; by comparison his show in Kraków at <a href="https://www.inyourpocket.com/krakow/tauron-arena-krakow_143558v">Tauron Arena</a> may feel like an intimate affair.
