Johnny Manuel is from Flint, Michigan. As a young child, he could not be pulled away from his radio and quickly began mimicking every note he heard coming out of the speakers. After covering a Run-D.M.C. song, he was signed to a record contract at the age of fourteen under the nickname Lil' Johnny. He was thrilled to be recording in studios and going on tour with famous artists. A couple of years later, however, he was dropped. As a 17-year-old, he locked himself into a room, depressed. He started working jobs in retail and other common jobs. He now hopes to return to the spotlight for a second chance while he presents himself and his music to the world.
