Question: What kind of group does U2 discography and Sunday Bloody Sunday have in common?

The War Tour was a concert tour by the Irish rock band U2, which took place in 1982 and 1983 in support of the group's third album "War".  The tour took place in Western Europe, the United States, and Japan, with new material from "War" taking an increasing role as the tour progressed.  Venues were mostly halls, but some arenas were introduced later on.  U2's performances were very well received both critically and commercially, especially in the United States where U2 broke through to become a major act.  Scenes of lead singer Bono waving a white flag during the song "Sunday Bloody Sunday" became an emblematic image of this phase of U2's career.  It was their first tour as full-time headlining act and their first to be profitable. <SEP>  It is the opening track from their 1983 album "War" and was released as the album's third single on 11 March 1983 in Germany and the Netherlands.  "Sunday Bloody Sunday" is noted for its militaristic drumbeat, harsh guitar, and melodic harmonies.  One of U2's most overtly political songs, its lyrics describe the horror felt by an observer of the Troubles in Northern Ireland, mainly focusing on the Bloody Sunday incident in Derry where British troops shot and killed unarmed civil rights protesters and bystanders. "Sunday Bloody Sunday" is a song by Irish rock band U2.  At the same time, the lyrics reject hate and revenge as a response, as noted in the line "There's many lost, but tell me who has won."  Along with "New Year's Day," the song helped U2 reach a wider listening audience.  It was generally well received by critics on the album's release. <SEP> Laurence Joseph Mullen Jr. (born 31 October 1961) is an Irish musician and actor, best known as the drummer of the Irish rock band U2.  Mullen's distinctive drumming style developed from his playing martial beats in a childhood marching band, the Artane Boys Band.  Some of his most notable contributions to the U2 catalogue include "Sunday Bloody Sunday", "Pride (In the Name of Love)", "Where the Streets Have No Name", "Zoo Station," "Mysterious Ways", and "City of Blinding Lights". <SEP>  The band formed at Mount Temple Comprehensive School in 1976 as teenagers.  In 1979, the group issued their first release, the EP "U2-3", which sold well in Ireland.  The following year, the group signed to Island Records and released their debut album, "Boy".  It reached number 52 in the UK and number 63 in the US.  They followed it up with the release of "October" (1981) and "War" (1983).  "War" was a commercial success, becoming the band's first number-one album in the UK while reaching number 12 in the US.  The album yielded the singles "Sunday Bloody Sunday" and "New Year's Day" and have since become among the band's most popular songs. The discography of Irish rock band U2 consists of thirteen studio albums, one live album, three compilation albums, sixty-seven singles, and eight extended plays (EPs).  On the subsequent War Tour, the group recorded the live album "Under a Blood Red Sky" and concert film "", both of which sold well and helped establish them globally as a live act.
