Question: Are Bryan Ferry and Toshiko Koshijima both singers?
Context: Bryan Ferry CBE (born 26 September 1945) is an English singer and songwriter.  His voice has been described as an "elegant, seductive croon".  He also established a distinctive image and sartorial style; according to "The Independent", Ferry and his contemporary David Bowie influenced a generation with both their music and their appearance. The Jazz Age, is the fourteenth studio album, is a rerecording of some of Bryan Ferry's compositions, as played in jazz style of the 1920s, by The Bryan Ferry Orchestra.  The 13 songs have been chosen from 11 albums, from his very first release "Roxy Music" (1972) to his at that time recent solo record "Olympia" (2010).  The album was co-produced by Ferry and Rhett Davies, with arrangements by Colin Good, and released on 26 November 2012 as a 10in vinyl folio edition and on 12in vinyl, CD and digital download, on BMG Rights Management. Cutie Cinema Replay is the second album by the Japanese electronica band Capsule.  The album was released in 2003 and, unlike the other releases of the group, nearly every track features a guest vocalist.  Toshiko Koshijima sings on only two tracks, "Plastic Girl" and "Music Controller".  Some tracks on the album have a French theme, with the intro and outro both spoken in French by the group member and producer Yasutaka Nakata, while "French Lesson" has "123" and "ABC" being said in French with accordion being played in the background. Yasutaka Nakata (中田 ヤスタカ , Nakata Yasutaka , born February 6, 1980 in Kanazawa, Ishikawa) is a Japanese DJ, record producer, composer and songwriter.

World of Fantasy is the twelfth studio album by the Japanese electronica band Capsule, released on May 25, 2011, in Japan.  The album was originally due for release with the title of "Killer Wave".  After the 2011 Tōhoku earthquake occurred on March 11, 2011, Yasutaka Nakata announced that the album's release (which was previously announced as March 23, 2011) was postponed and due for release at an unknown date for cover art rework and renaming.  "Killer Wave" was then considered a "working title".  This is the only album of the duo with all songs sung by the vocalist Toshiko Koshijima.  It is also their first completely English-language album. Capsule (カプセル , Kapuseru ) is a Japanese electronica band consisting of record producer Yasutaka Nakata and vocalist Toshiko Koshijima. The Bryan Ferry Orchestra is a retro-jazz ensemble founded and led by Bryan Ferry.  They exclusively play his work in a 1920s jazz style.  Ferry formed the orchestra out of a desire to focus on the melodies of his songs, and "see how they would stand up without singing".  Their album, "The Jazz Age", was released on 26 November 2012 as a 10in vinyl folio edition and on 12in vinyl, CD and digital download, on BMG Rights Management Ferry neither plays nor sings with the orchestra; BBC reviewer Chris Roberts called it "[a] peculiar concept then, with Ferry now, almost Warhol-like, sagely mute to one side while collaborators silkscreen his own icons.  As fascinating as it is perplexing, anything but obvious, and therefore to be applauded." Oliver Thompson is an English guitarist, songwriter and singer.  He has toured with Roxy Music and Bryan Ferry since 2005, playing with guitarists such as Phil Manzanera, Chris Spedding and Johnny Marr.  He has played on Bryan Ferry's solo tours, festival dates and recording projects since he began working with Ferry at age 17.
