French dad Joel turned to nightly doses of classical music from artists like Mozart and Beethoven to get rid of the men who were routinely smoking, drinking and allegedly dealing drugs near his home.
It started out with Joel singing himself.
"I don't know what came over me. I opened the window and I started shouting the Little 'Green Mouse' (Souris verte) or 'My Little Rabbit' (Mon petit lapin)," he told Le Parisien. "It was a peaceful solution to take back our property."
Realizing that his repertoire was somewhat limited, Joel began using recordings to keep the dealers away.
"They asked me why I was doing it," Joel said. "I told them their noise bothered me."
In addition to Mozart and Beethoven, Joel also turned to pieces like "The Nutcracker" by Tchaikovsky.
Some of the dealers have fought back by playing rap music, but Joel was vowed that the classical program will go on. "I filed a complaint with the police. But I'm not going to stop," he said. "Their behavior is unacceptable."
