You're talking about the choral version of Malaika, and not the Low Tide Theme song right?
That choral group is OK, but frankly, I heard better choral groups in Kenya--even high school groups.
One reason Malaika kind of stands out in East Africa, is that the music is not usually of the same quality as other parts of Africa (IMO). To my ear, Zairian music, and stuff from Zimbabwe like Thomas Mapfumo, is far superior as far as musicianship and beauty is concerned. Some of the competitive a cappella stuff in Kenya was OK, but generally the music you here on the street is raucous, tinny and poorly played. The Kenyans must like it though. In contrast, Malaika is sweet and tonal. BTW, you'd think Kenyans would be listening to contemporary African American music, but actually American Country is much more popular there. They're all farmers, no matter what occupation they have.
