Agustin's first novel, La Tumba (The Tomb) was the brief but provocative story of a Mexican upperclass teen, deemed indecent by the public but gathering praise from older writers. This and his most famous work, De Perfil (Profile view), a fast and detailed view of three days in the main character's life, show stylistic similarities to James Joyce's work, especially A Portrait of the Artist as a Young Man.
He was considered a member of the so-called Onda literature, onda (wave) being slang for current and fashionable views in the eyes of young people.
A common technique in his work is mixing character's speech with narrative, without making any kind of distinction,(free indirect discourse). Thus the reader finds a long dialogue written in a single sentence,and is expected to realize which character is speaking as he reads the words. He also makes use of the stream of consciousness technique.
Como libro de critica musical deja mucho que desear, a todos los artistas de pendejos no los baja, excepto a su ex novia Angélica María. Como libro sobre la historia de la contracultura, del rock en un país que siempre ha reprimido a los jóvenes que no obedecen como borregos lo que los represores mandan, es indudablemente un buen texto.
