At the time of the live recording at Slane Castle, U2 was experiencing significant acclaim and commercial success following the release of their album "The Joshua Tree" in 1987, a landmark record that propelled them to international stardom. The concert, which took place in 2001, was part of their "Elevation Tour" promoting the album "All That You Can't Leave Behind." This album marked a return to a more melodic and spiritually resonant sound, featuring popular tracks like "Beautiful Day" and "Stuck in a Moment You Can't Get Out Of." The performance itself at Slane Castle was notable for its intimate yet grand setting, allowing the band to connect deeply with their Irish audience. U2's reputation for electrifying live performances was solidified during this era, as they continued to evolve their sound while engaging with themes of love, faith, and social justice, elements that were frequently woven into their concerts.
