Question: What person was the frontman of the band Emigrate, Richard Z. Kruspe or Tim Lambesis?
Context: Emigrate is the first full-length self-titled studio album by the European band Emigrate.  This album was released August 31, 2007 in Europe and was released in the United States and in Australia on January 29, 2008 but still has no Worldwide release dates. Timothy Peter "Tim" Lambesis (born November 21, 1980) is an American extreme metal musician, producer, and convicted felon, best known as the founding member and lead vocalist of American metalcore band As I Lay Dying.  He also had a solo/side thrash metal project in tribute to actor Arnold Schwarzenegger, Austrian Death Machine, in which he performed all the instruments.  He also formed a death metal band called Pyrithion and played guitar for Society's Finest and Point of Recognition. Frail Words Collapse is the second studio album by American metalcore band As I Lay Dying.  The album is their first release on the record label Metal Blade Records.  Only two of the five current band-members (drummer Jordan Mancino and frontman Tim Lambesis) appeared on the album.  Two of the band's signature songs, "94 Hours" and "Forever", appear on the album. Richard Zven Kruspe (born Zven Kruspe; 24 June 1967 in Wittenberge) is a German musician and guitarist of the German Neue Deutsche Härte band Rammstein, as well as the frontman of the band Emigrate. "New York City" is the first single by the musical group Emigrate.  The promo version of the single has an alternative cover.  The gas mask has a burning building instead of a woman reflected in lenses.  It has been considered the band's most successful song, so far.  Richard, in the music video, can be seen walking through New York City and sitting down and singing.  The song has been credited by many as a phenomenon, as Richard Z. Kruspe does not show his guitar skills, like he does with Rammstein, but now sings as the main vocalist and does what Till Lindemann states as "[An] incredible job at singing and makes the song perfect in every way, who would have known my fellow German guitarist would now be singing in great American dialect, I'm very proud of Rick". Emigrate is an American alternative metal band based in New York City, led by German Richard Z. Kruspe, the lead guitarist of the Neue Deutsche Härte band Rammstein.

Total Brutal is the debut full-length album by Austrian Death Machine, a project of As I Lay Dying's vocalist Tim Lambesis.  The band and record are based upon Arnold Schwarzenegger and his movies.

Destroy the Runner vocalist Chad Ackerman voices all of the Schwarzenegger impersonations.  The album was released on July 22, 2008.
