Roger Waters wants to add a new song to his renown "The Wall" concert this year.
2013 will be the first time his show tours open-air venues around the world - something Waters has always wanted to do.
The new song is called "The Ballad Of Jean Charles De Menezes", which tells the real story of a man who was shot dead by police in London in the wake of terrorist attacks and fear in the city.
"It's a surprise to people," Waters said of the song. "They've never heard it before."
The new show adds brand new special effects. One example: the plane crash sequence has doubled in length and ends in a "spectacular fireball" thanks to new HD technology and a bigger stage set.
