Context: Ten Notes on a Summer's Day is Crass's final album under the Crass name.  It was released in 1986 and consists of a vocal and instrumental version of the same tracks in an avant-garde musical style. Antonio Buonomo (born in Naples in 1932) is an Italian composer, solo percussionist and music educator.  Professor of percussion at the conservatories of "S.Pietro a Majella in Naples" of Naples and "S.Cecilia" of Rome, Antonio Buonomo’s professional experience includes performing as timpani soloist in various orchestras (such as the "San Carlo" of Naples and "La Fenice" of Venice) and director of one of Europe’s first all-percussion instrument groups.  His many compositions and transcriptions for percussion instruments have been published by the main houses of this sector and include teaching materials as well as music for plays and television documentaries.  They have been performed for the occasion of prestigious avant-garde musical events, television and radio programs as well as in public concerts. The V.I.P.s were a British R&B musical ensemble formed in Carlisle, Cumberland, (North West England) in late 1963, out of an earlier outfit known as The Ramrods, who had formed in Carlisle in 1960.  After a change of personnel in April 1967, the band changed their name to "Art", and released the album "Supernatural Fairy Tales".  They also participated to a psychedelic bizarre album called "Featuring The Human Host And The Heavy Metal Kids" by a collective known as Hapshash and the Coloured Coat, formed by Guy Stevens and an influential British graphic design and avant-garde musical partnership between Michael English and Nigel Waymouth.  The musicians involved in that project were Mike Harrison on keys and vocals, Luther Grosvenor on guitars, Greg Ridley on bass and Mike Kellie on drums, as well as performances by Stevens, English and Waymouth.  It was the first time that the term "heavy metal" was ever used in music, even though that album had nothing to do with heavy metal music, being closer to psychedelic music.  That album was published in 1967 on Liberty Records and contained only five songs from two minutes to more than 15 minutes of psychedelic and almost meditative state kind of music. Erwin Ratz (22 December 1898, Graz – 12 December 1973, Vienna) was an Austrian musicologist and music theorist.  He studied musicology with Guido Adler and composition with Arnold Schoenberg and was active in the Schoenberg circle.  In 1921 and 1922, due to straightened financial circumstances, he worked at the Bauhaus in Weimar as a secretary.  After World War II he was a professor of musical form and analysis in Vienna.  He is best known for his work "Einführung in die musikalische Formenlehre" ("Introduction to Musical Form"), which is devoted primarily to the work of Bach and Beethoven, and for his role in editing Mahler's works as President of the 'International Gustav Mahler Gesellschaft' in Vienna.  From 1960 Ratz fought against the efforts of Deryck Cooke and others to create performable editions of Mahler's unfinished Tenth Symphony, insisting in articles and interviews that no such attempt could be legitimate given the state of Mahler's draft. Art rock is a subgenre of rock music that generally reflects a challenging or avant-garde approach to rock, or which makes use of modernist, experimental, or unconventional elements.  Art rock aspires to elevate rock from teen entertainment to an artistic statement, opting for a more experimental and conceptual outlook on music.  Influences may be drawn from genres such as experimental rock, avant-garde music, classical music, and jazz. The St Luke Passion (full title: Passio et mors Domini nostri Jesu Christi secundum Lucam, or the Passion and Death of Our Lord Jesus Christ According to St Luke) is a work for chorus and orchestra written in 1966 by Polish composer Krzysztof Penderecki.  The work (one of several musical settings of the Passion story) contains text from the Gospel of Luke as well as other sources such as the Stabat Mater.  Despite the "Passion's" almost total atonality and use of avant-garde musical techniques, the musical public appreciated the work's stark power and direct emotional impact and the piece was performed several more times soon after its premiere on 30 March 1966.
