Heavy Sound was founded by former rapper Jordan Butler, who was homeless by the age of 13 and a victim of physical and sexual assault, with a history of addiction to drugs and alcohol.
One teenager, quoted in the GCU research, said: “At the end of it, I’m a different person and it’s helped me a lot. I learned how to be more confident in front of people.
“I used to be a bam. This project has made me think maybe I’m not all of that because I have been trying and a lot of things have been going good in my life now.”
