João Carlos Martins is a famous Brazilian classical pianist and conductor. He has played in many of the world's greatest concert halls. However, his career hasn't been easy and his life has taken him in many different directions,
João Carlos Martins was born in 1940. He learned to play the piano when he was a child and as a teenager he performed in concerts around the world. But when he was in his late twenties, he had to stop playing the piano after he broke his arm very badly while playing soccer. It was a terrible time for Martins. For four years he couldn't look at a piano. He couldn't even listen to classical music
Eventually, he decided to become the manager of a boxer from Brazil. When the boxer won the world championship a year and a half later, Martins looked at him and thought that if this man could be champion, then he could play the piano again. So he took up the piano again and practised for longer and longer every day. Then in 1974, he gave his first big concert in six years, at the Carnegie Hall in New York. There were over 3,000 people there and they loved his performance. It was the most amazing moment of his life. He performed in concerts for another seven years, but then he had to give up because of Repetitive Strain Injury (RSI), an extreme pain in his hands caused by too much playing. This time, Martins, now in his early forties, became ... a politician
However, Martins couldn't stand being a politician so, once again, he went back to the piano. All was going well until one day, in 1995, a terrible thing happened. As he was leaving a concert, two men attacked him. He suffered a serious brain injury and lost all the movement in his right hand. But Martins didn't want to give up. He kept playing, but just with his left hand. A few years later, he lost the use of his left hand and became a conductor. Now, in his eighties, Martins is still working and has conducted more than a thousand concerts in his career.
