Another Way to Use Your Voice to Make a Living

I can still remember the first time I listened to a So You Want to Be an Auctioneer cassette tape. I was about 13 on a road trip to Colorado, and I remember being amazed that someone could make a living just by using their voice in an interesting way. 

Something still captivates me about the ability, akin to freestyle rapping, to communicate information within the confines of rhythm and patter.
