Shortly before Christmas last year, Brazilian piano player Joao Carlos Martins invited his friends to a bar near his home in Sao Paolo. He wanted to show them the best gift he had received in many years, a new pair of gloves. They are not just any gloves, however. The specially made bionic devices are letting the 79 year old play with both hands for the first time in more than 20 years. The artist is considered one of the greatest players of the music of Johann Sebastian Bach.
