This cd is reasonably priced and has great examples of well-known tall tales. It took a minute for my small kids to quiet down as we listened in the car, but once they did, they were hooked.
The narration is engaging and lively, and I found myself visualizing what was being described. There really are no drawbacks in my opinion. I would suggest listening to the cd before the kids do so you can make a note of what needs to be introduced or explained before they hear it, for example where tall tales originated from, why they are called that, etc.
I am a proponent of books on tape and book/cd sets, and this cd gives listeners a chance to visualize scenes on their own. A great discussion after listening might be to compare how listeners “saw” things differently from each other.
