I have not found any other good podcasts on that matter.
There is a radio show called Exploring Music which goes through a lot of music in a similar way. I listen to that on TuneIn radio.
Another thing that I have found is that my local library has copies of the "How to Listen to and Understand Great Music" by Robert Greenberg. They are really good at going through the history of the music and then breaking down a lot of the forms.
They are expensive by themselves so look for them at a library.
