Question: Are both Throwing Muses and Grouplove American bands?

Context paragraphs:
Kristin Hersh: Kristin Hersh (born August 7, 1966) is an American singer, songwriter and author, known for her solo work and with her rock bands Throwing Muses and 50FootWave.  She has released ten solo albums.  Her guitar work and composition style ranges from jaggedly dissonant to traditional folk.  Hersh's lyrics have a stream-of-consciousness style, reflecting her personal experiences.

Throwing Muses (1986 album): Throwing Muses is the 1986 debut album of the band Throwing Muses, released on British independent label 4AD.  This was the first album by an American band to be released on 4AD, which had concentrated primarily on British-based acts up to this point.  The release marked a shift in the label's direction; a year later 4AD would sign Pixies based in part on the band's connection to the Muses, and by the mid-1990s much of the label's roster was made up of American bands.

Caulfield Sisters: The Caulfield Sisters (2000–present) are a critically praised independent band based in Brooklyn, New York, noted at times for their sonic similarity to Throwing Muses or Galaxie 500.  They have appeared at the annual CMJ music festival in New York, were featured in the New York art magazine "Esopus" and in an April 2005 live performance on Seattle independent radio station KEXP, and have performed with bands such as Interpol.

Lakuna: Lakuna was an electronic instrumental project begun by drummer David Narcizo after Throwing Muses first split up following their 1996 "Limbo" album.  Lakuna first released a 12-inch called "So Happy" and then a 1999 full-length album called "Castle of Crime."  Narcizo provided drums, drum programming, and keyboards on all the tracks.  The album's guest musicians included Bernard Georges on bass, Kristin Hersh on guitar loops, Belly's Tom Gorman on bass, Melissa "Misi" Narcizo on piano and keyboards, and Frank Gardner on bass and bass synthesizer.  Narcizo employed tape loops and samples from obscure, vintage music to achieve the album's ambient-styled instrumental sounds.  Lakuna recorded on the 4AD and Throwing Music labels.

Throwing Muses: Throwing Muses is an alternative rock band formed in 1981 in Newport, Rhode Island, that toured and recorded extensively until 1997, when its members began concentrating more on other projects.  The group was originally fronted by two lead singers, Kristin Hersh, and Tanya Donelly, who both wrote the group's songs.  Throwing Muses are known for performing music with shifting tempos, creative chord progressions, unorthodox song structures, and surreal lyrics.  The group was set apart from other contemporary acts by Hersh's stark, candid writing style; Donelly's pop stylings and vocal harmonies; and David Narcizo's unusual drumming techniques eschewing use of cymbals.  Hersh's hallucinatory, febrile songs occasionally touched on the subject of mental illness, more often drawing portraits of characters from daily life or addressing relationships.

Grouplove: Grouplove (also typeset as GROUPLOVE) is an American band that was formed in 2009 by Hannah Hooper (vocals, keyboards), Christian Zucconi (vocals, guitar), Sean Gadd (bass), Andrew Wessen (guitar, vocals), and Ryan Rabin (drums).

Hips and Makers: Hips and Makers is the debut solo album by Kristin Hersh, best known as the primary singer and songwriter of the band Throwing Muses.  The album was released by 4AD in the UK on January 24, 1994, and by Sire Records in the US on February 1, 1994.  In contrast to Hersh's rock-oriented work with Throwing Muses, the album is primarily acoustic, with Hersh usually playing unaccompanied.  Other credited musicians include Jane Scarpantoni on cello and Michael Stipe of R.E.M., who sings backing vocals on the opening track, "Your Ghost."  In addition to Hersh's own material, the album features a cover of the traditional song "The Cuckoo".

Limbo (album): Limbo is a 1996 album by the American alternative rock band Throwing Muses, released on Rykodisc.  The album was recorded at the same New Orleans studio the band recorded "University".  Following a tour for the album, Throwing Muses were dissolved, with Kristin Hersh continuing her solo career and David Narcizo and Bernard Georges working on several personal and music projects including Hersh's.  The album, engineered by Trina Shoemaker, also features cellist Martin McCarrick and Robert Rust on piano.

The Breeders discography: The discography of American alternative rock band The Breeders consists of four studio albums, one live album, three extended plays, ten singles and twelve music videos. Kim Deal, then-bassist of American alternative rock band the Pixies, formed The Breeders as a side-project with Tanya Donelly, guitarist of American alternative rock band Throwing Muses.  After recording a demo tape, The Breeders signed to the English independent record label 4AD in 1989.  Their debut studio album "Pod" was released in May 1990, but was not commercially successful.  After the revival of the Pixies and Throwing Muses in 1990, The Breeders became mostly inactive until the Pixies' breakup in 1993.  With a new lineup, The Breeders released their "Safari" EP in 1992, followed by their second studio album "Last Splash" in 1993.  "Last Splash" was The Breeders' most successful album; it peaked at number 33 on the United States "Billboard" 200 and was certified platinum by the Recording Industry Association of America in 1994.  The album spawned the band's most successful single, "Cannonball".  The single peaked at number 44 on the US "Billboard" Hot 100 and at number two on the "Billboard" Alternative Songs chart.

Throwing Muses (2003 album): Throwing Muses is an album by the alternative rock band Throwing Muses.  It was recorded over three weekends and released simultaneously with Kristin Hersh's solo record "The Grotto" on 17 March 2003.  The album features Bernard Georges on bass and David Narcizo on drums as well as original bandmate Tanya Donelly on backing vocals.
