Brad Steiger is one of the hard working giants in this field. I was delighted and honored to spend an hour in conversation listening to his deep, hypnotic voice. He shares many of his owl personal experiences, and he comes across as less an author and more of a mystic.
There is another excellentinterview with Brad from 2011 (linked HERE). These two interviews will play well side-by-side, creating (in a sort) a full two-hour interview. The order doesn't matter, and none of the information overlaps. Each of these audio interviews are just a little over one-hour long.
