A while back we were having a discussion about a cappella singing. I had completely forgotten about this, but I was reminded when browsing YouTube. If you saw David Lynch's movie "Mullholland Drive", then you saw an a cappella singer doing it the way it should be done. If not, then check out this clip from the movie. Rebecca Del Rio singing Llorando. Maybe you'll recognise the song even though it's in Spanish. She was written into the movie specifically because David Lynch was given a tape of her singing this song a cappella. IMHO, this really hits the mark.
