Article 1
I believe that the first article I chose "Pat Martino, Jazz Guitarist Who Overcame Amnesia, Dies at 77," would be categorized as a news article. It shares the facts about Martino's life and career, and it contains stories told by those who knew him. The author of the article does not make any judgments about Martino or his performances, only sharing how he was acclaimed and revered by others. Because of this strict adherence to factual information, this article is a news article and not a music review.
Article 4
The second article I chose, "Fidelio review - musically excellent but panopticon staging is overloaded," is definitely a music critic's review. Even though there is a great deal of factual information about the production, on the main photo the performance is given 3 out of 5 stars, and the author writes about how "Herbert is a tremendous Leonore," the music director "propels the score forward," and "The choral singing is excellent." These statements are not quotes of other people, but they are the opinions of the author himself. For this reason, it is a music review.
