KU has mature and rich alto. I have listened Choirs perform live and watched some on RU-vid....trust me hata alto ya Harmonious Chorale from Ghana and Mormon Tabernacle from US haiwezifikia KU. Whoever is in charge of this great choir please don't waste these precious jewels (alto). In fact, keep them together. It may take you 50 years for you have such a powerful voice!!! I stand to be challenged on this but after you have sampled at least 10 Choirs!
