My experience has more to do with the range of the experimental and avant-garde than any body of recorded work - my laboratory is my personal vehicle, and the voice-over work occurs while commuting to and from work, or on long car trips (the latter often punctuated with constructive criticism form wife and daughter) as well. Of course it's only avant-garde if those other drivers around me pay any attention at all, so that's the experimental part as well. Only once did a cop pull me over for excessive animation and let me off with just a warning (he sounded like Broderick Crawford) and a license check.
I have recorded celebrity impressions on telephone answering machines for our family and friends, but I've learned that many people circulate such numbers merely to listen to the impression and not to actually leave information, so that's at a real standstill at the moment.
My profession of social work requires me to spend six or seven hours listening and talking to people, so that really is my essential resource. I do perform dramatic interpretation at my local church, where I was trained in a traditional S-A-T-B choir beginning in 1966, also appeared in a Gilbert and Sullivan show ("Patience," 1993) as a favor to a friend and had a literal ball with the language in that farce.
In summary, I am seeking to trailblaze into this extremely interesting field as an "artist-naif," which loosely translated means "incredibly egotistical for such lack of experience and dearth of training." I am open to opportunities to be mentored or apprenticed (little or no compensation) if there is a credible source out there looking for a limited challenge.
