You would have to create a special category just for him. For those who don't know Eric, he used to sing Gospel with "Five Alive" back in the day. The group split up and Eric is the only one still singing to date. He might have been experimenting on this CD, hence the different languages, rythms, etc, or might have wanted to capture all Kenyans' attention, hence, the lingala, jazz, etc.
I have a very biased opinion here but I think he is AWESOME! He doesn't have a band, as yet-he was a student until not long ago at Berkley School of Music in Boston, and so just performed with other students there.

Yes, I am a hard-core fan since 1988!
