This might be my favorite thing I have found out there - The Jim Weiss audio CD's. My DS5 loves listening to anything in the car. I am so tempted to get the whole collection. We started with just downloading two - Tall Tales and King Arthur. Very high quality and very entertaining.
If you're looking for a history curriculum, and you like Jim Weiss, take a look (listen?) at Story of the World. We are partway through the second volume, but we aren't doing anything formal with it yet (just listening). I plan to start the first volume again, with activities, when we start school. Our local library had them on disc.
