I thought I could detect an accent in the men's singing, and indeed the group is a Slovenian chorus called Perpetuum Jazzile. This is their creative rendition of rock group Toto's Africa. (You can freshen your memory on the original in this live performance, or this music video.)
David Paich, who wrote the song, was so impressed with their version that he wrote them a note of high praise (click on News, then Toto loves us; coding doesn't let me link directly).
