You will be given a definition of a task first, then some input of the task.
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: "City of Angels" is a synthrock song with influences and elements from experimental music. It opens with an instrumental section and "gently burbling" synthesizers. It follows with the sounds of drum beats, including taiko drums, then transitions into a piano melody. After the first verse, the chorus follows, with Leto singing, "Lost in the City of Angels / Down in the comfort of strangers / I found myself in the fire burned hills / In the land of a billion lights". During the bridge, he ornaments his vocal lines with melodic crescendos, affirming "I am home". After the final chorus, the song reaches a drum-heavy climax. Emily Zemler from Billboard cited "City of Angels" as an example of variety and experimentation in Love, Lust, Faith and Dreams. She described the song as a "pulsating, subtler track that employs a blipping electronic beat rather than the band's usual rock backdrop".In a preview of the record, Jeff Benjamin from Fuse acknowledged the 1980s influences that resonated throughout the track and noted that "hard rock guitars and percussion come crashing in on the chorus." Sarah O' Hara, while reviewing Love, Lust, Faith and Dreams for Lowdown, compared the song to "Kings and Queens", a track with a similar structure included on This Is War featuring sparse verses and slow atmospheric builds to the chorus. In an interview with Loudwire, Leto described "City of Angels" as a very personal song about a specific place. He said, "It's the story of my brother and I going to Los Angeles to make our dreams come true. It's a love letter to that beautiful and bizarre land." Leto later explained that the song could refer to any place a person goes to fulfill his or her own dreams. Mary Ouellette, writing for Loudwire, felt that the song "tells a passionate tale of finding comfort in calling the city of Los Angeles home.".
Output:
What is the last name of the person who described "City of Angels" as a "pulsating, subtler track that employs a blipping electronic beat rather than the band's usual rock backdrop"?
