Sound of White Noise is the sixth studio album by American heavy metal band Anthrax, released in May 1993 on Elektra Records. It is the band's first album to feature vocalist John Bush, who replaced longtime Anthrax vocalist Joey Belladonna in 1992. It is also Anthrax's last studio album with longtime lead guitarist Dan Spitz.
The album, produced by the band and Dave Jerden, includes the singles "Only", "Black Lodge", "Room for One More" and "Hy Pro Glo". This album marked a significant revision in the band's sound, with the departure of lead vocalist Joey Belladonna and the introduction of grunge influences (Dave Jerden was the producer of Alice in Chains). Typical thrash metal elements such as speed and aggression, which characterized much of Anthrax's earlier work, are largely absent from their sound at this juncture in their career. The album debuted at No. 7 on the Billboard 200 charts, Anthrax's highest ever chart position. Sound of White Noise was certified gold by the RIAA. "Only" and "Black Lodge" charted at No. 26 and No. 38 respectively on the Billboard Hot Mainstream Rock Tracks chart.
The album's closing track "This Is Not an Exit" is directly based on the Bret Easton Ellis novel American Psycho. The lyrics through the song are in narrative towards the main character in the book, Patrick Bateman. This song also includes a sample from the 1991 movie My Girl. A music video was produced for the song "Black Lodge", featuring actress Jenna Elfman in one of her first film appearances. The Black Lodge is a fictional location in the popular early 1990s television series Twin Peaks. Anthrax were able to persuade Twin Peaks' score conductor Angelo Badalamenti to help compose the song.
Dave Connolly reviewed the album on behalf of Allmusic, giving the album three stars out of five. Connolly called the album "surprising melodic" but "predictably pummeling" and the music "relentless." He commends the overall quality of the songs on the album before settling on "Only" as the best overall, but calls out several other tracks for praise as well.
Among the album's songs, "Only" has received particular attention; Metallica frontman James Hetfield is said to have referred to "Only" as a "perfect song."
- The intro ("This is a journey into sound") is a sample of "Train Sequence" narrated by Geoffrey Sumner.
- The song "Black Lodge" was omitted from the vinyl release due to time.
- Anthrax also contributed a song from these sessions called "Poison My Eyes" to the Last Action Hero soundtrack.
- The title "Hy Pro Glo" is a reference to a television commercial for Purina Hi Pro Dog Food.
- The title "C11H17N2O2S Na" is the chemical formula for sodium pentothal, more commonly known as "truth serum".
