While doing paperwork today  I decided to finally take the time to check out Voices.com's podcast feature,   "Voiceover Experts" that you can subscribe to for free using iTunes or by just going directly there:

You may need to first be a member. (I'm not certain, but probably) If you are already a member and haven't investigated these 'casts, they're availability is  definitely a nice benefit.

Voice over Experts Podcasts

I enjoyed the brevity and succinct content, which suited my busy Saturday at the office. Hear some gems from industry heavyweights, movers and shakers as they discuss  their opinions and experiences regarding demos,  auditions, rejection, the value of good diction, marketing and sales.
