Browsing YouTube, I came across the Soweto Gospel Choir.
"The Soweto Gospel Choir was formed to celebrate the unique and inspirational power of African Gospel music ... The choir is dedicated to sharing the joy of faith through music with audiences around the world."
Currently touring in Europe, it would be nice if they are able to make it to the states in the next couple of years. Visit their site at http://www.sowetogospelchoir.com/.
