My experience started in my teens I had a band and often had to introduce the members so it was necessary to alter my voice so I would sound different from my performing voice. Latter serving in the U.S.Army 82nd Airborne during the Viet Nam era as a weapons instructor well you get the picture had to get there attention as to the seriousness of just what they were learning. After the Army I went on to have my own Jazz band as the led singer for more that 20yrs. I have worked with young youth as a youth director so I learn to be stearn but affective in San Diego.
Basically it has all been thru real life experiences and there is no room for mistakes at best. Have went to some workshops in the past in the 90s,as I stated earlier I,m a true entertainer in every since of the word.
Have no studio at this time.
