Which indie rock band's 1999 album '69 Love Songs' is a three-disc concept set?

The Magnetic Fields made 69 Love Songs, the three-disc concept set released in 1999. It is the sixth studio album by the American indie pop and rock group, arriving through Merge Records on September 7, 1999.

The project contains exactly 69 songs, divided into three volumes of 23 tracks each. Every song was written by Stephin Merritt, the group’s principal songwriter and frontman. Despite its title, the album ranges across country, synth-pop, chamber pop, folk, free jazz, and theatrical balladry rather than presenting one consistent musical style.

Merritt originally imagined the material as a stage revue. He was inspired partly by hearing a pianist perform Stephen Sondheim songs in a Manhattan gay piano bar and partly by Charles Ives’s collection 114 Songs. The result became an unusually large and varied examination of romantic love, often using irony, melodrama, and dark humor.

A frequent mistake is giving Stephin Merritt as the answer. Merritt wrote the songs and led the project, but The Magnetic Fields is the band credited with the album. The original release appeared both as a box set and as three separately catalogued volumes.
