Please answer the following question: Information:  - Classical music is art music produced or rooted in the traditions of Western music, including both liturgical (religious) and secular music. While a more accurate term is also used to refer to the period from 1750 to 1820 (the Classical period), this article is about the broad span of time from roughly the 11th century to the present day, which includes the Classical period and various other periods. The central norms of this tradition became codified between 1550 and 1900, which is known as the common-practice period. The major time divisions of Western art music are as follows:  European art music is largely distinguished from many other non-European and some popular musical forms by its system of staff notation, in use since about the 16th century. Western staff notation is used by composers to indicate to the performer the pitches (e.g., melodies, basslines, chords), tempo, meter and rhythms for a piece of music. This can leave less room for practices such as improvisation and "ad libitum" ornamentation, which are frequently heard in non-European art music and in popular-music styles such as jazz and blues. Another difference is that whereas most popular styles adopt the song (strophic) form, classical music has been noted for its development of highly sophisticated forms of instrumental music such as the concerto, symphony, sonata, and mixed vocal and instrumental styles such as opera which, since they are written down, can sustain larger forms and attain a high level of complexity.  - Yessongs is the first live album by the English rock band Yes, released in May 1973 on Atlantic Records. The album is a compilation of recordings taken from their "Fragile" (1971) and "Close to the Edge" (1972) tours between February and December 1972, from various locations in North America and the Rainbow Theatre in London. Two tracks feature Bill Bruford on drums; the remaining songs feature his replacement, Alan White.  - "And You and I" is the second track from the album "Close to the Edge" by the English progressive rock band Yes. The song is just over ten minutes in length and consists of four movements. The first and second parts of the song were released as a single edit and reached #42 on the "Billboard" Hot 100.  - `` Siberian Khatru '' is the third , shortest and final song on the album Close to the Edge by English progressive rock band Yes . Live versions of the song are included on the albums Yessongs , Keys to Ascension , Live at Montreux 2003 and In the Present -- Live from Lyon . Multiple performances of the song are included on the 2015 boxed - set Progeny : Seven Shows from Seventy - Two , which features seven complete consecutive concerts recorded on the band 's late 1972 North American tour .  - Live at Montreux 2003 is a 2007 live album from the English progressive rock band Yes. It is a live recording of the group's headlining concert at the Montreux Jazz Festival on 14 July 2003. The performance was filmed and is also available on DVD/Blu-ray.  - Progressive rock (shortened as "prog"; sometimes "art rock", "classical rock" or "symphonic rock") is a broad subgenre of rock music that developed in the United Kingdom and United States throughout the mid to late 1960s. Initially termed "progressive pop", the style was an outgrowth of psychedelic bands who abandoned standard pop traditions in favour of instrumentation and compositional techniques more frequently associated with jazz, folk or classical music. Additional elements contributed to its "progressive" label: lyrics were more poetic, technology was harnessed for new sounds, music approached the condition of "art", and the studio, rather than the stage, became the focus of musical activity, which often involved creating music for listening, not dancing.  - King Crimson are an English rock band formed in London in 1968. The band has undergone numerous formations throughout its history of which 21 musicians have been members; since January of 2017 it has consisted of Robert Fripp, Jakko Jakszyk, Tony Levin, Mel Collins, Pat Mastelotto, Gavin Harrison, Bill Rieflin and Jeremy Stacey. Fripp is the only consistent member of the group, and is considered the band's leader and driving force. The band has earned a large cult following.  - A double album (or double record) is an audio album which spans two units of the primary medium in which it is sold, typically records and compact discs. A double album is usually though not always released as such, because the recording is longer than the capacity of the medium. Recording artists often think of double albums as comprising a single piece artistically; however, there are exceptions such as John Lennon's "Some Time in New York City" and Pink Floyd's "Ummagumma" (both examples of one studio record and one live album packaged together) and OutKast's "Speakerboxxx/The Love Below" (effectively two solo albums, one by each member of the duo). A classic example of this idea is Works (Volume One) by Emerson Lake and Palmer, where side one was Keith Emerson, two Greg Lake, three Carl Palmer while side four was by the entire group.  - Close to the Edge is the fifth studio album by the English progressive rock band Yes, released on 13 September 1972 by Atlantic Records. Following a tour in support of their previous album, "Fragile", Yes returned to Advision Studios in London to record their next album. Produced by the band and audio engineer Eddy Offord, the album consists of three tracks: "Close to the Edge" on side one; "And You and I" and "Siberian Khatru" on side two. When recording for the album finished, drummer Bill Bruford, frustrated by the band's style and laborious recording in the studio, left to join King Crimson.  - DVD (an abbreviation of "digital versatile disc" or "digital video disc") is a digital optical disc storage format invented and developed by Philips, Sony, Toshiba, and Panasonic in 1995. The medium can store any kind of digital data and is widely used for software and other computer files as well as video programs watched using DVD players. DVDs offer higher storage capacity than compact discs while having the same dimensions.  - Atlantic Recording Corporation (simply known as Atlantic Records) is an American record label founded in October 1947 by Ahmet Ertegün and Herb Abramson. Over its first 20 years of operation, Atlantic Records earned a reputation as one of the most important American recording labels, specializing in jazz, R&B and soul recordings by African-American musicians including Aretha Franklin, Ray Charles, Wilson Pickett, Sam and Dave, Ruth Brown and Otis Redding, a position greatly enhanced by its distribution deal with Stax Records. In 1967, Atlantic Records became a wholly owned subsidiary of Warner Bros.-Seven Arts, now the Warner Music Group, and expanded into rock and pop music with releases by bands such as Led Zeppelin and Yes.  - Richard Christopher "Rick" Wakeman (born 18 May 1949) is an English keyboardist, songwriter, television and radio presenter, and author. He is best known for being in the progressive rock band Yes across five tenures between 1971 and 2004 and for his solo albums released in the 1970s.  - Eddy Offord is a former record producer and recording engineer, who worked on some of the most famous progressive rock albums of the 1970s, often at London's Advision Studios. He is especially well known for his work with the groups Emerson, Lake & Palmer and Yes. ELP wrote a tribute to Offord with the song "Are You Ready, Eddy?", featured on their 1971 album "Tarkus". Chris Squire of Yes described Offord's influence on their album "Fragile" with the following words: "Eddy Offord's maturity as a producer and engineer gives "Fragile" the sonic depth and sophistication it deserves and this made the album in fact 'fragile'".  - William Scott "Bill" Bruford (born 17 May 1949) is a retired English drummer, percussionist, songwriter, producer, and record label owner who first gained prominence as the original drummer of the rock band Yes, from 1968 to 1972. After his departure from Yes, Bruford spent the rest of the 1970s playing in King Crimson, touring with Genesis and U.K., and forming his own group, Bruford.  - London is the capital and most populous city of England and the United Kingdom, as well as the most populous city proper in the European Union. Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it "Londinium". London's ancient core, the City of London, largely retains its medieval boundaries. Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly.  - Keys to Ascension is a double album by the English rock band Yes, released in October 1996. Following the return of guitarist Steve Howe and keyboardist Rick Wakeman into the band's line-up in 1995, the group performed three concerts in San Luis Obispo, California in March 1996, recording seven tracks. Two tracks were recorded in a studio.     After reading the paragraphs above, we are interested in knowing the entity with which 'siberian khatru' exhibits the relationship of 'producer'.
