Anderson is an excellent professor. He knows the material well, knows how to present it well, and (though sometimes he makes it clear that he really doesn't agree) is interested in what the students have to say.
The texts we read (from the Magic Flute to Sebald) are uniformly good reads. This is one of the few heavy reading (relatively heavy, often a novel a week, though sometimes just some poetry) classes I had in which I've done all the reading and wanted to do it.
Don't expect too much music though. Anderson is a literature prof. He seems to be a big music fan, but it's not his area. With some of the works the connection to music is pretty much abandoned. That said, some of the connections were really insightful.
If you'd like to have the opportunity to read a lot of the highlights of German Literature, have intelligent discussions about them, and get some credit, take this class.
