"Great Introduction with well-placed sample clips"
Yes, because the audio edition has the distinct advantage of inline samples from important pieces being discussed, which makes it interactive in a way that a print version (even one that includes a CD with samples) cannot be.
Since this was a historical survey, it's hard to choose a favorite character! But I did enjoy learning about the Red Priest, Giuseppe Verdi.
Experience pronouncing the sometimes difficult foreign words.
No, I enjoyed the episodic nature, though I found some of the chapters to be rather long (upwards of an hour), which made it difficult to put down when I needed to do something else!
I'd make sure to download this in High Quality, since it includes orchestral samples that would be less satisfying in a more muffled/lower-quality setting.
"Awful"
I purchased this looking for a nice diversion, and was sorely disappointed. The audio quality is terrible - there is no equalization of volume among voices, which makes it annoying to listen to. I had to keep turning it up and down to even hear what was taking place, which meant that my ears were blown out when characters screamed (which seems altogether too often).
Even worse, though the play is clearly set in Germany, the character accents are all 19th-century English, making for a particularly jarring performance.
Save yourself the time and pain.
