Every year I go back to the basics and tune my mouthcall skills (i'm pretty good making general calls, but can always improve). Unfortunately, all my stuff was in tape format from years gone by. I just got a new vehicle and it only has a CD player. So, I'm off to buy an instructional tape in CD format. Any recommendations as to whoseCD to get? I like the ones that arefor beginners and explain in detail how to make the sounds.

Thanks!
