Background: P. D. Q. Bach is a fictitious composer invented by musical satirist "Professor" Peter Schickele. Schickele developed a five-decade-long career, performing the "discovered" works of the "only forgotten son" of the Bach family. Schickele's music combines parodies of musicological scholarship, the conventions of Baroque and classical music, and slapstick. The name "P. D. Q." is a parody of the three-part names given to some members of the Bach family that are commonly reduced to initials, such as C. P. E., for Carl Philipp Emanuel Bach.
Context: Schickele's works attributed to P. D. Q. Bach often incorporate comical rearrangements of well-known works of other composers. The works use instruments not normally used in orchestras, such as the bagpipes, slide whistle, kazoo, and fictional or experimental instruments such as the pastaphone (made of uncooked manicotti), tromboon, hardart, lasso d'amore, and left-handed sewer flute. There is often a startling juxtaposition of styles within a single P. D. Q. Bach piece. The Prelude to Einstein on the Fritz, which alludes to Philip Glass' opera Einstein on the Beach, provides an example. The underlying music is J.S. Bach's first prelude from The Well-Tempered Clavier, but at double the normal speed, with each phrase repeated interminably in a minimalist manner that parodies Glass's. On top of this mind-numbing structure is added everything from jazz phrases to snoring to heavily harmonized versions of "Three Blind Mice" to the chanting of a meaningless phrase ("Koy Hotsy-Totsy," alluding to the art film Koyaanisqatsi for which Glass wrote the score). Through all these mutilations, the piece never deviates from Bach's original harmonic structure. The humor in P. D. Q. Bach music often derives from violation of audience expectations, such as repeating a tune more than the usual number of times, resolving a musical chord later than usual or not at all, unusual key changes, excessive dissonance, or sudden switches from high art to low art. Further humor is obtained by replacing parts of certain classical pieces with similar common songs, such as the opening of Brahms' Symphony No. 2 with "Beautiful Dreamer", or rewriting Tchaikovsky's 1812 Overture as the 1712 Overture, with "Yankee Doodle" replacing Tchaikovsky's melody, and "Pop Goes the Weasel" replacing "La Marseillaise".

Problem: Background: Alejandro Jodorowsky Prullansky (Spanish: [ale'xandro xodo'rofski]; born 17 February 1929) is a Chilean-French filmmaker. Active since 1948, in seventy years of his artistic career Jodorowsky has experienced it in almost all creative forms: writer (in his five facets: novelist, storyteller, poet, playwright and essayist), film director and producer, actor of cinema and theatre, playwright, theatre director, screenwriter, film editor, comics writer, musician, soundtrack composer, philosopher, puppeteer, mime, psychologist and psychoanalyst, draughtsman, painter, eventually sculptor and spiritual guru. Best known for his avant-garde films, he has been "venerated by cult cinema enthusiasts" for his work which "is filled with violently surreal images and a hybrid blend of mysticism and religious provocation". Born to Jewish-Ukrainian parents in Chile, Jodorowsky experienced an unhappy and alienated childhood, and so immersed himself in reading and writing poetry.
Context: In 1982 Jodorowsky divorced his wife. In 1989, Jodorowsky completed the Mexican-Italian production Santa Sangre (Holy Blood). The film received limited theatrical distribution, putting Jodorowsky back on the cultural map despite its mixed critical reviews. Santa Sangre was a surrealistic slasher film with a plot like a mix of Alfred Hitchcock's Psycho with Robert Wiene's "The Hands of Orlac". It featured a protagonist who, as a child, saw his mother lose both her arms, and as an adult let his own arms act as hers, and so was forced to commit murders at her whim. Several of Jodorowsky's sons were recruited as actors. He followed in 1990 with a very different film, The Rainbow Thief. Though it gave Jodorowsky a chance to work with the "movie stars" Peter O'Toole and Omar Sharif, the executive producer, Alexander Salkind, effectively curtailed most of Jodorowsky's artistic inclinations, threatening to fire him on the spot if anything in the script was changed (Salkind's wife, Berta Dominguez D., wrote the screenplay). That same year (1990), Jodorowsky and his family returned to live in France. In 1995, Alejandro's son, Teo, died in an accident while his father was busy preparing for a trip to Mexico City to promote his new book. Upon arriving in Mexico City, he gave a lecture at the Julio Castillo Theatre where once again he met Ejo Takata, who at this time had moved into a poor suburb of the city where he had continued to teach meditation and Zen. Takata would die two years later, and Jodorowsky would never get to see his old friend again.
