Richard Powers has a composer obsession, too

I have been reading the new Richard Powers novel, Playground, and I'm on page 141. Johann Sebastian Bach hasn't put in an appearance yet. 

I remarked once again yesterday about the role of Beethoven in RAW's works, and then I realized that Bach plays a similar role in Powers' works. This is most obvious in The Gold Bug Variations, which has a lot about Bach's Goldberg Variations (one of the main characters listens to Glenn Gould's famous 1950s recordings) but Bach is mentioned in many of Powers' other books. 

An interest in classical music also is a theme in Powers' books, most obviously in Orfeo. Here is my interview with Powers about that book. The official Richard Powers website has links to music mentioned in Orfeo. 

Of course, an interest in classical music pervades RAW's "Historical Illuminatus" books, and Mozart even appears as a minor character. 

I've read other works of fiction that mention classical music and specific composers, but when I tried to think of another modern writer who focuses in much of his/her work on one particular composer, I came up dry.

If it isn't obvious, I'm a huge Powers fan. I've read 11 of his 14 novels so far. Powers has won a National Book Award, a Pulitzer, a MacArthur "genius" grant, etc., so he's a good example of a writer embraced by the literary establishment, as opposed to RAW, who spent his life being pretty much ignored by it. I guess the issue is that RAW wasn't published as a "mainstream" writer, but it seems a shame he never got discovered by one of the major literary review magazines, got a lot of press in major newspapers or came up for any of the major literary awards. (Playground was listed as a nominee for the Booker Award even before it came out!)

Footnote: Classical music doesn't loom large in the works of Robert Shea (most of his novels are set in the Middle Ages, preceding such music) but from what I can tell reading his nonfiction bits, he had a particular interest in Mozart.
