Amazing! This is such a great experience for these children. Music production, song writing, and recording is not the easiest thing to do, especially when it comes to hip hop. It's great to see your students enjoying their time and creating wonderful pieces of music. Also, good job on choosing hip hop and rap. The hip hop genre is full of soul and knowledge, that not only entertains people, but also teaches them a great lesson. Keep on doing what you love and everything will definitely turn out great.
