Christopher Tin is the composer of Baba Yetu, Civilization IV soundtrack, arguably one of the best video games of all time.
I really recommend listening to his album, Calling All Dawns; the first track is Baba Yetu. Enjoy!
"Baba Yetu" is a song by composer Christopher Tin. It was composed in 2005 when video game designer Soren Johnson, his former roommate at Stanford, asked Tin to compose the theme song for Civilization IV and was sung by Ron Ragin and the Stanford Talisman. For its re-release in Tin's debut album Calling All Dawns, it was sung by Ron Ragin and the Soweto Gospel Choir. [Wikipedia]
Performed by InChorus, Lothian and Borders Police Choir and Tayside Police Choir at Edinburgh Festival Theatre in September 2012.
