Context paragraphs:
October Tour: The October Tour was a concert tour by Irish rock band U2 that took place in 1981 and 1982 to support the band's second studio album, "October", which was released in October 1981.

The Walls: The Walls are an Irish rock band.  They were formed in 1998 by two ex-members of The Stunning – brothers Steve and Joe Wall.  Their debut album "Hi-Lo" was released in 2000 and included the singles "Bone Deep", "Something's Wrong" and "Some kind of a Girl".  U2 invited The Walls to support them at their second show in Slane Castle in 2002 after the band sent them copies of their debut.  A number of songs from "Hi-Lo" featured in movies: Goldfish Memory, On the Edge, and Dead Bodies.  In 2002 they released the single "To the Bright and Shining Sun".  It was used on an Irish TV commercial and became a hit in Ireland.  The subsequent album "New Dawn Breaking" (2005) included "To the Bright and Shining Sun" and three other singles: "Drowning Pool", "Passing Through" and "Black and Blue".  The 2013 movie Begin Again starring Keira Knightley and Mark Ruffalo features "Drowning Pool" over the opening credits.  The first track on the album "Open Road" proved a favourite with Nic Harcourt on his KCRW show "Morning Becomes Eclectic" and he invited the band to play a session on the show in 2006.  They played SXSW in Austin, Texas, a few days beforehand.  The following year the band travelled to Australia and played their first shows there, opening up for Crowded House on the latter's first reunion gigs.  The Walls opened the shows in Sydney and Melbourne and also performed their own gigs in both of those cities.  The band's third album "Stop the Lights" was released in 2012.  The first single "Bird in a Cage" became a firm favourite with Irish radio, in particular with Irish DJ Tony Fenton who championed them.  The second single was the title track "Stop the Lights", an autobiographical story of a motorbike crash.  A video was shot for the song in the brother's hometown, Ennistymon, and in the Dublin mountains.  In March 2013 the band played their first shows in Russia and performed live on the Evening Urgant show.  They returned the following year.

City of Blinding Lights: "City of Blinding Lights" is a song by Irish rock band U2.  It is the fifth track on their 2004 album "How to Dismantle an Atomic Bomb" and was released as the album's fourth single on 6 June 2005.  The song was a top ten hit in Ireland, the United Kingdom, and several other countries.  The music video was shot in Vancouver, British Columbia.

The Unforgettable Fire: The Unforgettable Fire is the fourth studio album by Irish rock band U2.  It was produced by Brian Eno and Daniel Lanois, and released on 1 October 1984 by Island Records.  The band wanted to pursue a new musical direction following the harder-hitting rock of their 1983 album, "War".  As a result, they employed Eno and Lanois to produce and assist in their experimentation with a more ambient and abstract sound.  The resulting change in direction was at the time the band's most dramatic.  The album's title is a reference to "The Unforgettable Fire"—an art exhibit about the atomic bombing of Hiroshima.  The band saw the exhibit in November 1983 in Japan while on the "War" Tour.

The Táin (Horslips album): The Táin is a music album by Irish rock band Horslips.  Their second studio album, it was Horslip's first attempt at making a concept album, an idea they would return to in 1976 with "The Book of Invasions: A Celtic Symphony".  "The Táin" was based on the Táin Bó Cúailnge (The Cattle Raid of Cooley), one of the most infamous legends of Early Irish literature, dealing with the war between Ulster and Connacht over a prize bull.  The songs tell the story from the points of view of Cúchulainn, Queen Maeve of Connacht and Ferdia, among others.  Horslips continued their Celtic Rock style of fusing traditional Irish music and rock, using traditional jigs and reels and incorporating them into their songs.  For example, Dearg Doom is based on "O'Neill's March", while "The March of the King of Laois" forms part of "More Than You Can Chew".

Cold Sweat (Thin Lizzy song): "Cold Sweat" is a song by Irish rock band Thin Lizzy, and is the fifth track on their final studio album "Thunder and Lightning".  It was co-written by guitarist John Sykes and Phil Lynott, and became the biggest single from the album, entering the UK charts at No. 27, and peaking at No. 23 in Ireland.

Seven Secrets: Seven Secrets is the second studio album by North Irish progressive rock band Fruupp, released on 19 April 1974 in the United Kingdom on the Dawn Records label, a subsidiary of Pye Records for underground and progressive rock music.  Like the band's debut album, it was recorded at Escape Studios in Egerton, Kent, but was this time produced by David Lewis, the frontman of another North Irish rock band Andwella.

October (U2 album): October is the second studio album by Irish rock band U2.  It was produced by Steve Lillywhite, and released on 12 October 1981 on Island Records.  Inspired by Bono's, the Edge's, and Larry Mullen Jr.'s memberships in a Christian group called the "Shalom Fellowship", the record features spiritual and religious themes.  Their involvement with Shalom Fellowship led them to question the relationship between the Christian faith and the "rock and roll" lifestyle, and threatened to break up the group.

Fire (U2 song): "Fire" is a song by Irish rock band U2.  It is the fifth track on the band's 1981 album, "October", and was released that year as the album's first single.

The Stunning: The Stunning are an Irish rock band formed in 1987.  In the seven years that they were initially together, they toured relentlessly building up a following that would make them one of the most successful Irish bands ever.  In 1990 their debut album <nowiki>"</nowiki>Paradise In The Picturehouse<nowiki>"</nowiki> spent five weeks at number one and became one of the most-loved Irish albums of all time.  Two years later, the follow-up Once Around The World also hit the number one spot, and the band went on to sell over 100,000 albums in Ireland alone.  Brewing Up A Storm has become an anthem of sorts and is to be heard everywhere from football stadiums to clubs around the country where it is still a guaranteed floor-filler.  Songs such as Half Past Two, Romeo’s on Fire, and Everything that Rises is still to be heard on the radio and have been featured in movies and numerous compilation albums of the best of Irish rock.  They toured the US and the UK with the likes of Bob Dylan and The B52s.  During their time, the band scooped every music prize and award going and their music is still to be heard on the airwaves.  The band split up in 1994 to pursue other interests and they reformed in 2003 to support the re-release of their debut album "Paradise in the Picturehouse".  They perform regularly for select Irish shows and festivals, and in 2014 they returned to New York and Boston for their first gigs there since the early nineties.  The band are currently in the studio recording new material, set for release in early 2016.
