...incredibly complicated considering that it is only four people singing acapella. Music that is heavy on harmony is, in general, a favorite of mine. I even enjoy listening to the odd Christian group, though I am not a fan of religious music.
If you haven’t heard much of it, I recommend The Nylons, Rockappella, and Acapella to start with. If you are a member of the teenage female set, Boyz II Men has some good stuff, too.
