input: Jones, the founder and only remaining original member of Foreigner, decided to take some time off before looking to form a new lineup in 2004. On July 25, 2004 in Santa Barbara, California at Fess Parker's DoubleTree Resort, Jones appeared at a benefit show for muscular dystrophy with a brand new version of Foreigner that included: Jeff Jacobs, Thom Gimbel, former Dokken bass player Jeff Pilson, future Black Country Communion drummer Jason Bonham (son of Led Zeppelin drummer John Bonham and leader of Bonham) and Bonham singer Chas West. West was front man for that show only and was eventually replaced by former Hurricane singer Kelly Hansen, who had sent the band an audition tape and was invited aboard in March 2005, making his debut with the group on March 11 at Boulder Station near Las Vegas. During their 2005 spring tour, Chas West briefly continued with the band as a special guest, playing rhythm guitar. Their 2005 BMG album, Extended Versions, featured the new line-up playing all their classic hits live in concert in one of the most "studio like, clean sounding" live album recordings produced. Foreigner joined Def Leppard along with Styx on tour in 2007. They also toured extensively in their own right in 2007 - the thirtieth anniversary of the release of their debut. In late 2007, keyboardist Jeff Jacobs left Foreigner after 16 years and was replaced, first by Paul Mirkovich then by Michael Bluestein (in 2008). And in 2008, Bonham also parted ways with Foreigner. Bryan Head was then brought in to fill the drum chair. But his tenure was short and he also departed to be replaced by the returning Tichy. The band released a greatest hits anthology on July 15, 2008, titled No End in Sight: The Very Best of Foreigner. The anthology included all of their greatest hits plus some new live recordings and a new studio track, "Too Late", which was their first new song release since the 1994 album Mr. Moonlight and the first recorded output of the new lineup. "Too Late" was released as a single on June 17, 2008.

Question: Yellow Magic Orchestra (YMO) is a Japanese electronic music band formed in Tokyo in 1978 by Haruomi Hosono (bass, keyboards, vocals), Yukihiro Takahashi (drums, lead vocals) and Ryuichi Sakamoto (keyboards, vocals). The group is considered influential and innovative in the field of popular electronic music. They were pioneers in their use of synthesizers, samplers, sequencers, drum machines, computers, and digital recording technology in popular music, and effectively anticipated the "electropop boom" of the 1980s while exploring subversive sociopolitical themes throughout their career. YMO was initially conceived by Hosono as a one-off exploration of computerized exotica and parody of Western conceptions of the orient.

Prior to the group's formation, Sakamoto had been experimenting with electronic music equipment at the Tokyo National University of Fine Arts and Music, which he entered in 1970, including synthesizers such as the Buchla, Moog, and ARP. Hosono, following the break-up of his band Happy End in 1972, became involved in the recording of several early electronic rock records, including Yosui Inoue's folk pop rock album Kori no Sekai (1973) and Osamu Kitajima's progressive psychedelic rock album Benzaiten (1974), both of which utilized synthesizers, electric guitars, electric bass, and in the latter, electronic drums and rhythm machines. Also around the same time, the band's future "fourth member" Hideki Matsutake was the assistant for the internationally successful electronic musician Isao Tomita. Much of the methods and techniques developed by both Tomita and Matsutake during the early 1970s would later be employed by Yellow Magic Orchestra. Sakamoto first worked with Hosono as a member of his live band in 1976, while Yukihiro Takahashi recruited Sakamoto to produce his debut solo recording in 1977 following the split of the Sadistic Mika Band. Hosono invited both to work on his exotica-flavoured album Paraiso, which included electronic songs produced using various electronic equipment. The band was named "Harry Hosono and the Yellow Magic Band" as a satire of Japan's obsession with black magic at the time, and in late 1977 they began recording Paraiso, which was released in 1978. The three worked together again for the 1978 album Pacific, which included an early version of the song "Cosmic Surfin". Hosono and Sakamoto also worked together alongside Hideki Matsutake in early 1978 for Hosono's experimental "electro-exotica" fusion album Cochin Moon, which fused electronic music with Indian music, including an early "synth raga" song "Hum Ghar Sajan". The same year, Sakamoto released his own solo album, The Thousand Knives of Ryuichi Sakamoto, experimenting with a similar fusion between electronic music and traditional Japanese music in early 1978. Hosono also contributed to one of Sakamoto's songs, "Thousand Knives", in the album. Thousand Knives was also notable for its early use of the microprocessor-based Roland MC-8 Microcomposer music sequencer, with Matsutake as its music programmer for the album. While Sakamoto was working on Thousand Knives, Hosono began formulating the idea of an instrumental disco band which could have the potential to reach success in non-Japanese-language territories, and invited Tasuo Hayashi of Tin Pan Alley and Hiroshi Sato of Uncle Buck as participants, but they declined. Hosono, Sakamoto and Takahashi eventually collaborated again to form the Yellow Magic Orchestra and they began recording their self-titled album at a Shibaura studio in July 1978. The band was initially conceived as a one-off studio project by Hosono, the other two members being recruited session musicians--the idea was to produce an album fusing orientalist exotica with modern electronics, as a subversion of Orientalism and exoticization.
