Released on this day in 1988, Rattle and Hum is the sixth studio album by U2, and a companion rockumentary film directed by Phil Joanou. Following the breakthrough success of The Joshua Tree, the Rattle and Hum project captures U2's continued experiences with American roots music on the Joshua Tree Tour, further incorporating elements of blues rock, folk rock, and gospel music into their sound. A collection of new studio tracks, live performances, and cover songs, the project includes recordings at Sun Studios in Memphis and collaborations with Bob Dylan, B. B. King, and Harlem's New Voices of Freedom gospel choir. The film grossed just $8.6 million, but the album was a commercial success, reaching number one in several countries and selling 14 million copies. Lead single "Desire" became the band's first UK number-one song while reaching number three in the US.
