These are recorded videos of a continuing ed class being conducted by Vanderbilt U. in conjunction with the Nashville Symphony. The audio quality is iffy on the first two, especially the filmed 'Peter and the Wolf' performance presented as an in-class movie. However, as a beginner I found it well worth the minimal effort to get past the shaky audio, and the quality of the sound improved with the third class.
The symphony conductor and a senior college staffer alternate leading the class. There are six 90-minute classes at the time I posted this. It looks like these are being presented on a bi-weekly basis. I hope this course isn't over, but there are already episodes covering strings, brass and woodwinds, and percussion.
Now if I could just get those darn BBC .RAM files to play
