Doppelgänger is a much darker, more haunting album than the album that preceded it, ¡Alarma!. The album starts with the eerie backward sounds of "Hollow Man" (inspired by T. S. Eliot's poem, The Hollow Men). Taylor's lyrics to "I Didn't Build it For Me", "Autographs for the Sick", and "New Car" were sharp attacks on televangelists, anticipating the Jimmy Swaggart/Jim Bakker/Robert Tilton scandals of 1987–88.
Doppelgänger is the second of a four-part series of albums by DA entitled The ¡Alarma! Chronicles, which also includes the albums ¡Alarma!, Vox Humana, and Fearful Symmetry. The band raised eyebrows on the tour that followed each release, by presenting a full multimedia event complete with video screens synchronized to the music, something that was unusual in the early 1980s for any band. This album, along with the other three albums from the Alarma! Chronicles, was rereleased as part of the Alarma! Chronicles Book set in 2000. The Book Set included 3 CDs, over 200 pages of lyrics, photos, liner notes, essays, interviews and other information in a hardcover book.
