For a time I enjoyed the rambling, conversational prose of Henderson The Rain King as a sort of stream-of-consciousness-lite, but it eventually became annoying as the narrator would jump to past events that may have not been previously discussed to draw analogies with his current situation. This and the philosophical tone of much of the dialogue and reflection make the non-narrative parts of the story difficult to follow. I cannot shake the feeling that Bellow has some powerful thesis about life, love, personality, suffering, and the relationship between man and beast. Unfortunately, I cannot reconcile Henderson’s character with my own and am at a loss to explain the understanding that he finally seems to gain. If I am going to follow a man into deep Africa and catastrophe, I’ll take “the horror, the horror” over “I want, I want, I want”.

Dream Job, Or Giving Up?
I had the (mis)fortune of seeing Ke$ha on SNL last night, and it made me wonder: did her guitarist as a child hope to someday play mindless riffs that could barely be heard over synthesized bleeps and bloops while wearing a silver jumpsuit and space helmet? Somehow, I cannot imagine this being the case. My problem is not that he is a sideman or accompanist; the Band (Bob Dylan) and the Eagles (Linda Ronstadt) did so quite effectively, but they were essentially playing the same kind of music that they would choose to write themselves. Nor do I claim that hip-hop and rock & roll are mutually exclusive, having seen The Roots meld the two so well. But this performance was in no way synergistic.
My thought is that a lover of electro-pop and rap music would never choose to pick up the guitar, but would instead practice scratching records, mixing samples, singing, etc. The kinds of interests that would entice someone to learn to play guitar are exactly those that the music of Ke$ha repudiates. So does that guitarist actually love his work, or has he resigned himself to the fact that he will never be respected by his peers and accepted this as a way to monetize his talents? What about all of the instrumentalists supporting boy bands, pop divas, or American Idols? Have any of them ever gone on to successful careers of their own? Am I just closed-minded when it comes to musical genres?
It strikes me that you might ask the same question about the members of the house band on SNL and other late-night television shows? Most of those guys are jazz musicians who took an opportunity for a steady paycheck. They have to play commercially-acceptable music on these shows, but it does not seem quite so antithetical to their art. Certainly, members of these bands such as Michael Brecker, Lou Marini, Doc Severinsen, and Branford Marsalis have had acclaimed careers outside of those bands.

I Survived The Double Down
The new Double Down “sandwich” from KFC consists of bacon and cheese between two fried (or grilled, but let’s be serious here) chicken fillets. Naturally it has been the butt of jokes and commentary as a prime example of America’s unhealthful, gluttonous lifestyle. Given all of the hype and the fact that fried chicken, bacon, and cheese are among my very favorite foods, I had to give it a try.
I bought the fried variety, without the Colonel’s Special Sauce. (I am always leery of such things; it could be based on mayonnaise or something equally disgusting.) The chicken was surprisingly good, and consisted of an actual cut of meat rather than reconstituted chicken slurry. The bacon was bacon, which means it was amazingly delicious. I was disappointed in the pepper jack cheese, which was spicy yet retained the rubbery look and feel of American cheese-like product. I am glad to have had the experience, but do not expect that I will be eating another one in the near future. Bread does add a certain something to a sandwich, and I think I would rather have one of the fillets with bacon and cheese in a roll.
At 540 calories, this sandwich confirms my thesis that even eating terribly unhealthful foods it is difficult to reach 2000 calories. The sandwich was an entire meal for me, and I do not think the half cherry danish I ate this morning and 1/10 of a pan of lasagna I will eat tonight will contain 3 times as many calories. It does contain nearly half of the daily recommended intake of fat and more than half the recommended intake of sodium, and I am guessing that a large proportion of the fat is saturated. Fortunately, I recently read an article that questions the role of fat in obesity and heart disease.

MusicMap & Recommendations
MusicMap is a style of research that I have been interested in for some time, and hope to branch into at some point in my career. The idea is to provide a 2-dimensional model in which similar things are close to each other and dissimilar things are far away from each other. I could not find it stated explicitly anywhere, but my educated guess is that these relationships are based on data from last.fm, with the similarity between two musicians based on how frequently they appear together in the list of artists a user likes compared to how frequently only one of them appears.
There are legitimate questions as to whether or not the same people liking two artists really makes them “similar”, and the process of trying to embed very high-dimensional data into the plane inevitably results in artifacts that appear to affirm relationships that do not actually exist. Looking at this map, is the music of Duke Ellington really that similar to the music of Eminem and that distinct from Lee Morgan? Are Morgan and Ellington really more similar to Snoop Dogg than to each other and very far from Louis Armstrong? What does Garth Brooks have to do with rhythm & blues?
Not surprisingly, my own interests tend toward the extremes of the map, away from the vast desert of mainstream pop in the center of the continent and the northwestern electronica steppes. Start with the jazz musicians at the southwestern coast; move eastward through soul, funk, and blues to classic rock; drift northward through hard rock and into heavy metal (but avoiding the peninsula of extremism); then tiptoe to the northwest, sampling a taste of modern rock but never quite comfortable until you reach the punk coast; continue through to the peninsula of ska; and from there take a boat east to the isle of reggae. Where do you draw your own citizenship?
I created a last.fm account for myself a few months ago. If you too have an account, please be my “friend”. As a way to keep track of what I have listened to and look for trends, I find the service very useful. I am not so sure about its utility as a recommendation system, however. Last.fm uses what appears to be a binary model of interest: either you have listened to a musician or you have not. Perhaps they use weights based on how often you listen to a band, but the fact that some artists are much more prolific than others would complicate that. There is no easy way to differentiate between that which you love, like, or merely tolerate. (It is possible to “love” individual tracks, but I do not think that this is used for recommendations.) More importantly, there is no way to distinguish between musicians that you have not listened to because you are unaware of them and musicians that you have not listened to because you hate their music. Any system that attempts to learn without any negative examples is going to have serious difficulties.
Long ago I set out to create my own music recommender system for several class projects and my own interests, but found the task far too large for a single person. My system was to be album-based, so that it can work in spite of artists who have evolved significantly over their careers. Instead of the ambiguities in the last.fm data, users would be able to rate albums on a numeric scale, and would be encouraged to rank some music that they are familiar enough with to know that they do not like it. It would attempt to collect other data about albums (the year they were released, producers who worked on them, whether they are studio / live / compilations releases, etc) and about users (age, gender, geographical location, etc) to explicate how those features might explain some users’ ratings. Users would be able to generate custom recommendations by choosing an algorithm (k-means clustering, singular value decomposition, …) and a data source (user’s ranking, album data, user demographics) instead of the default. Unfortunately, even if I had been able to find the time to implement all of this, collecting all of this data from a large sample of the population would be impossible. That is the genius of last.fm; while the informative content of the data may be weak, it is collected automatically from people who opt-in.
I became a member of Pandora back when you actually had to pay for an account. I love the idea of their Music Genome Project attempting to find similarity based on actual musical characteristics, but they often seem to find the most superficial relationships while ignoring the factors that are important to me. Their system has a tremendous knowledge engineering requirement to determine the “genetic code” of each song, and it is amazing that they have been able to accomplish this feat. But does it actually make good recommendations? Only partially, in my experience. Based on a playlist of thrash and mainstream metal, it has selected the song “Hitman” by Metal Church for me. This is good; I like the song. But Pandora has played that song for me dozens of times and never any other track by Metal Church. It is possible that this is the one and only song they ever wrote in the style of music that I enjoy (I’ve not yet actively sought to hear the rest of their catalog), but this seems unlikely. If one of the objectives is to help me discover new music that I would like, then a little variety would be nice.

Book Review: Winesburg, Ohio
I described the U. S. A. trilogy as more a collection of mostly unrelated narratives than my conception of a novel, but I should have saved that description for Winesburg, Ohio, which is a collection of short stories about the inhabitants of a small town. While dos Passos usually followed his subjects through enough of their lives to develop significant characterizations, we see only a few minutes or a day in the lives of most of Sherwood Anderson’s characters. While the people are not unimportant, this is more a book of events and moments in time. Some of the individual stories are quite captivating, but most did not interest me.
