instruction:
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: In early 2005, Frusciante entered the studio to work on his fifth and final studio album with the Chili Peppers, Stadium Arcadium. His guitar playing is dominant throughout the album, and he provides backing vocals on most of the tracks. Although usually following a "less is more" style of guitar playing, he began using a full twenty-four track mixer for maximum effect. In the arrangements, he incorporates a wide array of sounds and playing styles, similar to the funk-influenced Blood Sugar Sex Magik or the more melodic By the Way. He also changed his approach to his playing, opting to contribute solos and allow songs to be formed from jam sessions. In an interview from Guitar World, Frusciante explained how he approached his guitar solos for their album Stadium Arcadium completely differently from those for their previous albums. On Blood Sugar Sex Magik and Californication, Frusciante had a general idea how he wanted his guitar solos to sound. For Stadium Arcadium, almost every guitar solo was completely improvised by Frusciante on the spot. Several reviews have stressed that the influence of Hendrix is evident in his solos on the album, with Frusciante himself backing this up. He also expanded the use of guitar effects throughout the album, and used various other instruments such as the synthesizer and mellotron. He worked continuously with Rubin over-dubbing guitar progressions, changing harmonies and using all his technical resources.Frusciante began a series of collaborations with friend Omar Rodriguez-Lopez and his band The Mars Volta, by contributing guitar and electronic instrumentation to song "Cicatriz ESP" off their album De-Loused in the Comatorium. He also contributed guitar solos on their 2005 album Frances the Mute. In 2006, he helped The Mars Volta complete their third album Amputechture by playing guitar on seven of its eight tracks. In return, Rodriguez-Lopez has played on several of Frusciante's solo albums, as well as making a guest appearance on Stadium Arcadium.
answer:
What is the name of the group that Frusciante provides backing vocals for?

Passage: After the publication of the L'Orfeo score in 1609, the same publisher (Ricciardo Amadino of Venice) brought it out again in 1615. Facsimiles of these editions were printed in 1927 and 1972 respectively. Since Eitner's first "modern" edition of L'Orfeo in 1884, and d'Indy's performing edition 20 years laterboth of which were abridged and adapted versions of the 1609 scorethere have been many attempts to edit and present the work, not all of them published. Most of the editions that followed d'Indy up to the time of the Second World War were arrangements, usually heavily truncated, that provided a basis for performances in the modern opera idiom. Many of these were the work of composers, including Carl Orff (1923 and 1939) and Ottorino Respighi in 1935. Orff's 1923 score, using a German text, included some period instrumentation, an experiment he abandoned when producing his later version.In the post-war period, editions have moved increasingly to reflect the performance conventions of Monteverdi's day. This tendency was initiated by two earlier editions, that of Jack Westrup used in the 1925 Oxford performances, and Gian Francesco Malipiero's 1930 complete edition which sticks closely to Monteverdi's 1609 original. After the war, Hindemith's attempted period reconstruction of the work was followed in 1955 by an edition from August Wenzinger that remained in use for many years. The next 30 years saw numerous editions, mostly prepared by scholar-performers rather than by composers, generally aiming towards authenticity if not always the complete re-creation of the original instrumentation. These included versions by Raymond Leppard (1965), Denis Stevens (1967), Nikolaus Harnoncourt (1969), Jane Glover (1975), Roger Norrington (1976) and John Eliot Gardiner. Only the composers Valentino Bucchi (1967), Bruno Maderna (1967) and Luciano Berio (1984) produced editions based on the convention of a large modern orchestra. In the 21st century editions continue to be produced, often for use in conjunction with a particular performance or recording.
answer:
What is the name of the work Hindemith's attempted period reconstruction of, was followed in 1955 by an edition from August Wenzinger?

Passage: For several years Pink Floyd had busied themselves with personal pursuits, such as filming and competing in the La Carrera Panamericana and recording a soundtrack for a film based on the event. In January 1993, they began working on a new album, returning to Britannia Row Studios, where for several days, Gilmour, Mason and Wright worked collaboratively, improvising material. After about two weeks, the band had enough ideas to begin creating songs. Ezrin returned to co-produce the album and production moved to the Astoria, where from February to May 1993, they worked on about 25 ideas.Contractually, Wright was not a member of the band, and said "It came close to a point where I wasn't going to do the album." However, he earned five co-writing credits on the album, his first on a Pink Floyd album since 1975's Wish You Were Here. Another songwriter credited on the album was Gilmour's future wife, Polly Samson. She helped him write several tracks, including, "High Hopes", a collaborative arrangement which, though initially tense, "pulled the whole album together," according to Ezrin. They hired Michael Kamen to arrange the album's orchestral parts; Dick Parry and Chris Thomas also returned. Writer Douglas Adams provided the album title and Thorgerson the cover artwork. Thorgerson drew inspiration for the album cover from the Moai monoliths of Easter Island; two opposing faces forming an implied third face about which he commented: "the absent facethe ghost of Pink Floyd's past, Syd and Roger". Eager to avoid competing against other album releases, as had happened with A Momentary Lapse, Pink Floyd set a deadline of April 1994, at which point they would resume touring. The album reached number 1 in both the UK and the US. It spent 51 weeks on the UK chart.Pink Floyd spent more than two weeks rehearsing in a hangar at Norton Air Force Base in San Bernardino, California, before opening on 29 March 1994, in Miami, with an almost identical road crew to that used for their Momentary Lapse of Reason tour. They played a variety of Pink Floyd favourites, and later changed their setlist to include The Dark Side of the Moon in its entirety. The tour, Pink Floyd's last, ended on 29 October 1994.

Who was assisted in writing several tracks?
