I've been reading a lot of non-fiction lately. I finished The Mask of Command a few weeks ago, then took about a week to read Will Leitch's God Save The Fan (during which time the author signed my copy at a book reading downtown). I'm currently enjoying Alex Ross' The Rest Is Noise, an overview of music of the 20th Century. Normally I try to alternate fiction with non-fiction, but I received a number of books as holiday gifts, all of which were in the non-fiction category, so I'm working my way through those now. In particular, I am fascinated by Ross' recounting of the history of atonality and the popular reaction to innovations in composition by Schoenberg, Webern, Berg, and Bartok. (I'm only 120 pages in, so no spoilers!)
When I'm done with The Rest is Noise, I have Stephen Colbert's book on my shelf, and the book about the guy who spent a year reading the Encyclopedia Britannica. My non-fiction parade looks like it's going to continue for a few more months.
