Despite his long and rich career, Peter Hammill is one of the most important "best kept secrets" of English rock. In 1967 he formed the group Van Der Graaf Generator while studying at the University of Manchester, a group that he led as guitarist, keyboardist, singer and composer until 1978. Van Der Graaf Generator was the darkest and most chaotic traveling companion of other British progressive bands. early seventies like King Crimson or Genesis, although it would be wrong to classify it under the label of symphonic or progressive rock. Parallel to his work with the band, Hammill began his career as a soloist in 1971 with more than 40 works released until 2015. A true artist, more interested in the authenticity of his art than in marketing rules, his work is impossible to label or to enclose in a formula; Alone or accompanied, he can unleash a barrage of electric fury or the most beautiful acoustic calm, rear up like the most philosophical of psychotics or dedicate an entire album to love songs, compose an opera based on a text by Poe or carry out spontaneous experimental works. He always has the song as the fundamental axis of his work. This is why important musicians from the most diverse backgrounds revere him, from Peter Gabriel to Johnny Rotten, including Luca Prodan, David Bowie, Jello Biafra, Roger Waters, Peter Murphy, Nick Cave, Robert Fripp, Marc Almond, Bruce Dickinson, Mark Smith, Thom Yorke or Steve Wilson, all who have been influenced in different ways. Owner of a unique and incomparable voice (capable of the most varied nuances), multi-instrumentalist and prolific composer, Hammill is also one of the greatest lyricists in the history of rock, an author with a poetic approach that transcends his artistic peers and establishes him as one of the main artists to emerge at the end of the 20th century. 

"Necromancers, Lighthouse Keepers and Forgotten Gardens" is an approach to his work, life and thoughts, carried out by the specialized journalist and writer Marcelo Gobello, who has shared several talks, interviews and moments with Hammill from 1992 to the present, fundamental for the preparation of this book, thus completing more than four decades of study of his work and career. The book begins with a writing by Peter Hammill himself (written exclusively for this work) where he addresses his Spanish-speaking followers, and has abundant unpublished graphic material. 

As critic Dave Simpson noted of Peter Hammill's work: “Guiding us through the darkness and allowing tantalizing, uplifting rays of light, his life's work is a metaphor for life itself.”
