Question: Which band is from American, A-ha or The Mountain Goats?

Context paragraphs:
We Shall All Be Healed: We Shall All Be Healed is the eighth studio album by The Mountain Goats.  The album focuses on semi-fictional accounts of band leader John Darnielle's years as a teenager, particularly his friends' and acquaintances' experiences in California and in Portland, Oregon as methamphetamine addicts.  As The Mountain Goats' official website puts it: "All of the songs on "We Shall All Be Healed" are based on people John used to know.  Most of them are probably dead or in jail by now."  Like "Tallahassee", but unlike the rest of Darnielle's repertoire up to its release, "We Shall All Be Healed" was recorded with a full band in a recording studio, and produced by John Vanderslice, as opposed to The Mountain Goats' previous practice of recording at home on a boom box with, at most, one or two backup vocalists or a bassist.  "Palmcorder Yajna" (the primary single), when played in concert, is often played with the backing of members of one or more of the opening acts on tour with The Mountain Goats.  The song "Cotton" was featured in an episode of the television series "Weeds".

Nothing for Juice: Nothing for Juice is the third studio album by the Mountain Goats.  It is the last Mountain Goats release to feature Rachel Ware on bass and backing vocals.

Mycoplasma ovipneumoniae: Mycoplasma ovipneumoniae is a species of "Mycoplasma" bacteria that most commonly inhabits and affects ovine animals.  "M. ovipneumoniae" is a respiratory pathogen of domestic sheep, domestic goats, bighorn sheep, mountain goats, and other caprinae that can both cause primary atypical pneumonia and also predispose infected animals to secondary pneumonia with other agents, including "Mannheimia haemolytica".  Several mechanisms are involved in the pathogenicity of "M. ovipneumoniae", including altering macrophage activity, adhering to the ruminants' ciliated epitheluim via its polysaccharide capsule, inducing the production of autoantibiodies to cilary antigens, and suppressive activity on lymphocytes, all of which are important factors that contribute to the disease in sheep and other small ruminants.  The bacterium also has the ability to act as a prediposing factor for other bacterial and viral infections.

The Mountain Goats discography: The Mountain Goats is an American, Durham, North Carolina-based band, led by American singer-songwriter John Darnielle.  Darnielle began recording in 1991, and is known for his highly literate lyrics and (until 2002) his lo-fi recording style.  The Mountain Goats' albums have featured a constantly changing line-up of musicians, with Darnielle the only constant; when performing live, the band commonly comprises only Darnielle backed by Peter Hughes on bass guitar and Jon Wurster playing drums.

Satanic Messiah: Satanic Messiah is an EP by the Mountain Goats released during the band's 2008 tour with Kaki King.  Recorded by John Darnielle, this EP was released on satanicmessiah.com as a "pay as you like" download, similar to Radiohead's In Rainbows.  The EP was also produced in a limited vinyl run of 666 and sold during the Mountain Goats and Kaki King tour "The Last Happy Night Of Your Life."  s of June 2010 , the EP is no longer available for free.

A-ha: A-ha (usually stylized as a"-h"a; ] ) is a Norwegian band formed in Oslo in 1982.  The band was founded by Morten Harket (vocals), Magne Furuholmen (keyboards) and Pål Waaktaar-Savoy (guitars).  The group rose to fame during the mid-1980s after being discovered by musician and producer John Ratcliff, and continued global success in the 1990s and 2000s.

Peter Hughes (musician): Peter Hughes is a multi-instrumentalist currently with the band the Mountain Goats.  During live performances, he accompanies leader John Darnielle on bass.  His first official recording with the band was 2002's "Tallahassee", and he has performed on every subsequent album up to 2017's "Goths", but he also sang backup vocals on the song "Cubs in Five" from the 1995 EP "Nine Black Poppies".  That year, the Mountain Goats also dedicated an EP to him, "Songs for Peter Hughes".

Tallahassee (album): Tallahassee is the seventh studio album by the Mountain Goats.  It was the band's second new album to be released in 2002, and it marked quite a few changes.  First of all, after releasing records (and cassettes) on small record labels such as Shrimper, Ajax, and Emperor Jones, "Tallahassee" was the first Mountain Goats album to be released on a widely known independent label, the British alternative rock label 4AD.  It was also the first Mountain Goats album to have an official single released, for the song "See America Right."

The Mountain Goats: The Mountain Goats (stylized "the Mountain Goats") are an American indie folk band formed in Claremont, California by singer-songwriter John Darnielle.  The band is currently based in Durham, North Carolina.

All Hail West Texas: All Hail West Texas is the sixth studio album by the Mountain Goats.  After the slight increase in production values on "The Coroner's Gambit" album of 2000, "All Hail West Texas" is the last Mountain Goats album recorded entirely on John Darnielle's trademark Panasonic RX-FT500 boombox.  It is also the last album by the Mountain Goats to only feature John Darnielle.
