Question: In what country was the Kraftwerk studio album which had the song "Metal on Metal" recorded?

<P0-S0> The discography of American country artist Melba Montgomery contains twenty nine studio albums, eleven compilation albums, sixty two singles, one charting B-side and five other appearances. <P0-S1>  Signing with United Artists Records in 1962, she recorded with George Jones on the self-penned "We Must Have Been Out of Our Minds". <P0-S2>  It reached the top three of the "Billboard" Hot Country Singles chart. <P0-S3>  The pair's follow-up "Let's Invite Them Over" reached the top twenty, as did its B-side. <P0-S4>  Jones and Montgomery issued their debut studio album "What's in Our Heart" in November 1963, which peaked in the top ten of the "Billboard" Top Country Albums list. <P0-S5>  They continued releasing albums together including "Close Together" (1966) and "Party Pickin"' (1967). <P0-S6>  In 1963, Montgomery's debut solo singles reached the top-thirty of the country songs chart and the following year, her first pair of solo studio albums were issued. <P0-S7>  She collaborated with Gene Pitney in 1965, releasing "Baby Ain't That Fine" that year. <P0-S8>  The song reached number fifteen and the duo then issued the studio album "Being Together" (1965). <P0-S9>  Between 1965 and 1968 Montgomery released six solo studio efforts on both United Artists and Musicor, including "Hallelujah Road" (1966) and "Don't Keep Me Lonely Too Long" (1967). <P0-S10>  Through Capitol Records, she recorded with Charlie Louvin in 1970 and "Something to Brag About", reached number eighteen in early 1971. <P0-S11>  The pair would release two studio albums together in 1971 and several more singles. <SEP> <P1-S0> El Lado Oscuro (en: "The Dark Side") is the second studio album by power metal band DarkSun, released in 2004. <P1-S1>  The band entered the studios at the end of 2003. <P1-S2>  Just like "El Legado", this album was recorded in Germany, with Ingo Cjavkoski in the production. <P1-S3>  This time the band had Dennis Ward on mixings. <P1-S4>  (who was better known for his work with Angra), and Lars Ratz (from Metalium) assisted on the vocals production. <P1-S5>  Once again the reviews were as good as they could possibly be, like "...it's a varied work, where power and heavy metal alternate and mi", and ""El Lado Oscuro" is a really good power metal album". <P1-S6>  Peavy Wagner (of Rage fame) performed vocals on a song, which was released as a bonus track on the album, entitled "Prisoners of Fate". <SEP> <P2-S0> Trans-Europe Express (German: Trans Europa Express ) is the sixth studio album by German electronic music band Kraftwerk. <P2-S1>  Recorded in mid-1976 in Düsseldorf, Germany, the album was released in March 1977 on Kling Klang Records. <P2-S2>  The album's themes were influenced by friends who suggested writing songs about the Trans Europ Express to reflect Kraftwerk's electronic music style. <P2-S3>  Critics have described the album as having two specific themes: a celebration of Europe and the disparities between reality and image. <P2-S4>  Musically, the songs on this album differ from the group's earlier Krautrock style with a focus on electronic mechanized rhythms, minimalism, and occasionally manipulated vocals. <SEP> <P3-S0> "Metal on Metal" is a song by Kraftwerk from their 1977 album "Trans-Europe Express".
