U2's Sphere residency

U2 members Adam Clayton, Bono, and The Edge with Las Vegas Sphere background.

Beginning on September 29, 2023, U2 commenced their first-ever concert residency at the Sphere in Las Vegas. This was a new venture for the band, they are used to touring stadiums and arenas around the world.

The residency was tied to U2's 1991 album, Achtung Baby. They commemorated the album by playing it in full for the very first time. This included tracks such as “So Cruel” and “Love Is Blindness” that haven't been touched by the band in decades.

They played 40 nights at the Sphere from September 29, 2023, through March 2, 2024. During the final show, U2 surprised their fans by playing “40” at the very end of their show. “40” is known as one of the band's signature concert-closers.

Notably, in Underwood's post, drummer Larry Mullen Jr. is not anywhere to be seen. He sat out of the 40-night residency and Krezip drummer Bram van den Berg sat in for him.

U2 is one of the biggest rock bands in the world. They are known for their hit songs like “Sunday Bloody Sunday” and “With or Without You.” Like Underwood, they have racked in several Grammys, winning 22 awards out of their 46 nominations.

Lately, U2 has been in the “Songs of” era. This began in 2014 with Songs of Innocence. Songs of Experience and Songs of Surrender subsequently followed. Additionally, Bono wrote a memoir, Surrender: 40 Songs, One Story and embarked on his own solo tour. Songs of Surrender tied in with Bono's memoir, as the band released 40 re-recorded versions of U2's past songs.
