Good to see so many people interested in storytelling. It's a powerful medium which many people love but which scares others! I work professionally as both a storyteller and a folk singer, often both at once and once you can get people to experience it they love it. You've got to get past that 'storytelling is for children' bit first though.
There's been a lot of research going on recently into the affects of the human voice too. Despite all these hi-tech gadgets you can't beat it!
