Question: Are Iamamiwhoami and Queens of the Stone Age both American bands ?

Context paragraphs:
Queens of the Stone Age: Queens of the Stone Age (sometimes shortened to QotSA or Queens) is an American rock band formed in 1996 in Palm Desert, California.  The band's line-up includes founder Josh Homme (lead vocals, guitar, piano), alongside longtime members Troy Van Leeuwen (guitar, lap steel, keyboard, percussion, backing vocals), Michael Shuman (bass guitar, keyboard, backing vocals), Dean Fertita (keyboards, guitar, percussion, backing vocals), and recent addition Jon Theodore (drums, percussion).

Lithic technology: In archeology, lithic technology refers to a broad array of techniques and styles to produce usable tools from various types of stone.  The earliest stone tools were recovered from modern Ethiopia and were dated to between two-million and three-million years old.  The archaeological record of lithic technology is divided into three major time periods: the Paleolithic (Old Stone Age), Mesolithic (Middle Stone Age), and Neolithic (New Stone Age).  Not all cultures in all parts of the world exhibit the same pattern of lithic technological development, and stone tool technology continues to be used to this day, but these three time periods represent the span of the archaeological record when lithic technology was paramount.  By analysing modern stone tool usage within an ethnoarchaeological context insight into the breadth of factors influencing lithic technologies in general may be studied.  See: Stone tool.  For example, for the Gamo of Southern Ethiopia, political, environmental, and social factors influence the patterns of technology variation in different subgroups of the Gamo culture; through understanding the relationship between these different factors in a modern context, archaeologists can better understand the ways that these factors could have shaped the technological variation that is present in the archaeological record.

Iamamiwhoami: iamamiwhoami is the electronic music and audiovisual project of Swedish musician and singer-songwriter Jonna Lee in collaboration with her long-time music producer Claes Björklund.

List of Queens of the Stone Age contributors: Queens of the Stone Age (also known as QOTSA or simply Queens) are a rock band from Palm Desert, California, United States, formed in 1997.

The only permanent member of the band is founder Josh Homme, with guitarist Troy Van Leeuwen having been a member since the release of the band's third studio album, "Songs for the Deaf", in 2002.  Bassist Michael Shuman and keyboardist and guitarist Dean Fertita both joined the band in 2007 to tour in support of its fifth studio album, "Era Vulgaris" (2007).

Kyuss / Queens of the Stone Age: Kyuss / Queens of the Stone Age is an EP by the American rock bands Kyuss and Queens of the Stone Age, released in December 1997 on Man's Ruin Records.  It features some of the final studio recordings by Kyuss while debuting guitarist Josh Homme's next project, Queens of the Stone Age.

Queens of the Stone Age (album): Queens of the Stone Age is the eponymous debut album by American rock band Queens of the Stone Age, released in September 1998 by Loosegroove Records.  It was primarily written and recorded by founding member Josh Homme and his former Kyuss bandmate Alfredo Hernández, with Hernández playing drums and Homme singing and playing the rest of the instrumentation as well as producing the album alongside Joe Barresi.  By the time of the album's release, bassist Nick Oliveri, also a former member of Kyuss, would join the band.  "Queens of the Stone Age" received generally positive reviews from critics, who placed it in the stoner rock genre and drew comparisons to krautrock bands such as Can and Neu!  as well as to Kyuss and other metal bands.

Cocaine Rodeo: Cocaine Rodeo is the debut studio album by American rock band Mondo Generator, released on Southern Lord Records in 2000.  It was compiled of material recorded by vocalist/bassist Nick Oliveri with Rob Oswald of Karma to Burn (drums), vocalist and guitarist Brent Malkus, and his ex-Kyuss bandmates.  Recorded in 1997, the material was shelved for three years due to Oliveri's full-time commitment to Queens Of The Stone Age.  Several of the songs were performed live by Queens Of The Stone Age, building up hype before the eventual release of the album.

Stone Age Complication: Stone Age Complication is an EP by Queens of the Stone Age containing six B-sides and cover versions.  Josh Homme has stated that this is the only Queens of the Stone Age album released without any input from him or the band.

Gamma Ray (EP): Gamma Ray is the debut EP by Gamma Ray, a musical project by former Kyuss guitarist Josh Homme, released in 1996 by Man's Ruin Records.  After the breakup of Kyuss in 1995, Homme recorded the Gamma Ray material in Seattle with producer Chris Goss, bassist Van Conner, and drummer Victor Indrizzo.  Former Kyuss singer John Garcia contributed backing vocals to the track "Born to Hula".  After the release of the EP, Homme received a cease and desist order because the name Gamma Ray was already in use by a German band.  He changed the name of the project to Queens of the Stone Age, and both of the "Gamma Ray" tracks were re-released the following year by Man's Ruin on the "Kyuss / Queens of the Stone Age" split EP, which featured some of the final studio recordings by Kyuss and debuted the "Queens of the Stone Age" moniker for Homme's new project.  The split EP also included a third track from the "Gamma Ray" recording sessions, "Spiders and Vinegaroons".
