Iconic musician Prince Rogers Nelson, known to the world simply as Prince, has died in his Minnesota recording studio at the age of 57, according to TMZ.

“The singer — full name Prince Rogers Nelson — had a medical emergency on April 15th that forced his private jet to make an emergency landing in Illinois. But he appeared at a concert the next day to assure his fans he was okay. His people told TMZ he was battling the flu.”

A pioneer of the Minneapolis sound (a mixture of funk, rock, pop, synth, and new wave), Prince was nominated for 32 Grammys and won seven. Throughout this year, Prince had been playing surprise intimate shows throughout North America on his Piano and Microphone tour. At one of his latest stops on March 26 in Toronto, he performed 57 songs, five encores, and a cover of David Bowie’s “Heroes.”
