Question: In what did year did the Irish rock band from Dublin who the Fray were opening for when they debuted their song "Heartbeat" form?

LiR is an Irish rock band.  Their sound has been described as "a fusion of funky progressive rock, folky mysticism and savvy pop".  The band formed in the late 1980s in Dublin, firstly under the name The Spontaneous Frogs, then Uproar.  They released their first EP, 'All Machines Hum in A', in 1992.  In 1993, they released their first LP, 'Magico Magico!'  under the label Velo Records (Velo was an Irish Indie) in Ireland.  In 1994, they re-released 'Magico Magico!'  to the US, under the independent record label What Are Records?  (W.A.R.?) .  The new version of the album saw a revision to the track listing.  LiR would release their second album, 'Nest', exclusively with W.A.R.? , the following year, in 1995.  Around this time, they were notorious for playing constant live shows in Whelan's Bar, on Wexford Street in Dublin.  The support act was regularly by another Dublin band called Dragonfly (the lead guitarist of Dragonfly later became LiR's second guitarist, after the departure of keyboardist David Hopkins).  The LiR song 'Temple Child' appeared on the What Are Records?  "Ammunition" compilation album, a music sampler of various independent artists.  In 1997 the band appeared on the soundtrack for the movie "I Went Down", with the song 'There Are More Things'. <SEP>  The group consists of Bono (lead vocals and rhythm guitar), the Edge (lead guitar, keyboards, and backing vocals), Adam Clayton (bass guitar), and Larry Mullen Jr. (drums and percussion). U2 are an Irish rock band from Dublin formed in 1976.  Initially rooted in post-punk, U2's musical style evolved throughout their career, yet has maintained an anthemic sound built on Bono's expressive vocals and the Edge's effects-based guitar textures.  Their lyrics, often embellished with spiritual imagery, focus on personal and sociopolitical themes.  Popular for their live performances, the group have staged several ambitious and elaborate tours over their career. <SEP>  The band premiered the song while opening for U2 on their U2 360° Tour in May 2011.  The song was released for airplay on October 8, 2011, and was released for download in the United States on iTunes on October 11, 2011. "Heartbeat" is the first single from The Fray's third album "Scars & Stories". <SEP> 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.
