Robert Thomas Christgau is an American essayist and music journalist. Christgau is known for his terse, letter-graded capsule album reviews, first published in his "Consumer Guide" columns during his tenure at The Village Voice from 1969 to 2006. He has authored three books based on those columns, including Christgau's Record Guide: Rock Albums of the Seventies (1981) and Christgau's Record Guide: The '80s (1990), along with two collections of essays.

In this visualization, I visualized over Robert's over 16,000 graded reviews and presented the distribution of the album reviews to the years and to the grade letter. In the reviews, he graded an album among A+, A, A-, B+, ***, **, *, S, N, B, B-, C+, C, C-, D+, D, D-, E+, E, E-, X . A+is the highest grade meaning "this is a record of sustained beauty, power, insight, groove, and/or googlefritz that has invited and repaid repeated listenings in the daily life of someone with 500 other CDs to get to" and E- is, of course, the opposite. The specific grading critiria can be found here. The reviews are divided into two categories: albums and soundtracks.

In this review page, I visualized some interesting fact about the content of the reviews. For example, some Robert's most used words, most of which are mentioned artist, important albums or genres. Second visualization shows involves sentiment analysis of Robert's reviews. The sentiments are described in two dimensions: polarity and subjectivity. The polarity score is a float within the range [-1.0, 1.0]. The subjectivity is a float within the range [0.0, 1.0] where 0.0 is very objective and 1.0 is very subjective. This is made possible by Python library Textblob.
