The story goes that one day in 1979, Theodore was messing around on his brother's turntables, practicing his mixing skills so that he could DJ at parties in the Bronx. As is natural with all teenagers, he had his music up too loud. His mother started banging on the door and yelling at him. In order to listen to her, he put his hand on the record to stop it. He still wanted to keep the groove going, and found himself moving the record back and forth with his hand. It produced a sound he liked, and after his mother left, he spent weeks perfecting this technique, and finally unveiled it at a party during his mix.
