Question: Which band is from London, Alkaline Trio or World Party?
Context: Alkaline Trio / Smoking Popes is a split single by the Chicago-based rock bands Alkaline Trio and Smoking Popes.  It was distributed to attendees at a New Year's Eve performance by both bands at the Metro Chicago on December 31, 2006 – January 1, 2007.  The single features each band covering one of the other's songs, with Alkaline Trio covering the Smoking Popes' "Off My Mind" (from "Get Fired") and the Smoking Popes covering Alkaline Trio's "Blue Carolina" (from "Good Mourning"). Alkaline Trio is an American alternative rock band from McHenry, Illinois.  The band consists of guitarist and vocalist Matt Skiba, bassist and vocalist Dan Andriano, and drummer Derek Grant.  Founded in late 1996 by Skiba, bassist Rob Doran, and drummer Glenn Porter, Alkaline Trio released its debut single, "Sundials", in 1997.  Following its release, Doran departed from the band and was replaced by Andriano.  The band subsequently recorded an EP, "For Your Lungs Only" (1998), and its debut studio album, "Goddamnit" (1998).  Following the release of the band's second album, "Maybe I'll Catch Fire" (2000), Porter left the band and was replaced by Mike Felumlee for its subsequent album, "From Here to Infirmary" (2001). I Lied My Face Off is an EP by the Chicago-based punk rock band Alkaline Trio, released July 20, 1999 through Asian Man Records.  It resulted in the band's first music video, for the song "Goodbye Forever".  All four tracks from the EP were reissued on the compilation album "Alkaline Trio" in 2000. Demos is the first full-length album by Alkaline Trio singer/guitarist Matt Skiba.  It is composed of demos that Skiba has recorded into his computer.  Skiba released the project on Asian Man Records, which was Alkaline Trio's label for their first two full-length albums, "Goddamnit" and "Maybe I'll Catch Fire".  Four of the songs from this release, namely "Angel of Deaf," "Haven't You," "How The Hell Did We Get Here," and "Nausea (Cruel and Unusual)," were later rerecorded and released on "Babylon", Skiba's first album with his band The Sekrets.  On that release, however, "Nausea (Cruel and Unusual)" underwent lyrical alterations and was renamed "Olivia." Alkaline Trio / Blue Meanies is a split single between the Chicago-based punk rock band Alkaline Trio and the Carbondale, Illinois-based ska punk band the Blue Meanies, released as a picture disc in 2000 by Thick Records. Alkaline Trio / Hot Water Music is a split EP by the Chicago-based punk rock band Alkaline Trio and the Gainesville, Florida-based punk rock band Hot Water Music, released January 22, 2002 through Jade Tree.  In addition to new material, the EP features each band performing cover versions of songs from the other band's catalog, with Alkaline Trio covering Hot Water Music's "Rooftops" (from "No Division") and Hot Water Music covering Alkaline Trio's "Radio" (from "Maybe I'll Catch Fire") and "Bleeder" (from "I Lied My Face Off").  It was Alkaline Trio's first release with drummer Derek Grant, who replaced previous drummer Mike Felumlee in 2001. The discography of Alkaline Trio, a Chicago-based punk rock band, consists of nine studio albums, two compilation albums, one split album, four EPs, one video album, sixteen singles, one demo, nine digital releases, and thirteen music videos. Alkaline Trio formed in 1996 with an initial lineup of Matt Skiba (guitar, vocals), Rob Doran (bass guitar, backing vocals), and Glenn Porter (drums).  This lineup released the band's demo tape and the 1997 single "Sundials" on Chicago record label Johann's Face Records, after which Doran left the band and was replaced by Dan Andriano.  The group then signed to Asian Man Records and released their debut EP "For Your Lungs Only" and album "Goddamnit" in 1998.  A second EP, "I Lied My Face Off", followed in 1999 and resulted in their first music video, for the song "Goodbye Forever".  In 2000 Asian Man released the band's second album, "Maybe I'll Catch Fire", as well as the compilation album "Alkaline Trio", collecting most of their previously released early material.  Porter then left and was replaced by Mike Felumlee. World Party is a British alternative rock band, which is essentially the solo project of its sole member, Karl Wallinger.  He started the band in 1986 in London after leaving The Waterboys. For Your Lungs Only is the debut EP by the Chicago-based punk rock band Alkaline Trio, released May 26, 1998 through Asian Man Records.  The song "Southern Rock" was re-recorded for their debut album "Goddamnit" later that year.  All four tracks from the EP were reissued on the compilation album "Alkaline Trio" in 2000. "Sundials" (stylized as "Sun Dials") is the debut single by the Chicago-based punk rock band Alkaline Trio, released in 1997 by Johann's Face Records.  It is the band's only studio release to include original bassist Rob Doran, who left the group after the single's release and was replaced by Dan Andriano.  Both tracks from the single were reissued on the compilation album "Alkaline Trio" in 2000.
