Believe is the second studio album by the American metal band Disturbed. It was released on September 17, 2002. Believe debuted at number 1 on the Billboard 200 chart, making it Disturbed's first number 1 debut, shipping over 284,000 copies in its first week. It was certified double platinum by the RIAA in the United States on September 23, 2008.
The album contains three successful singles and focuses heavily on religious and spiritual themes inspired by recent tragedies. With greater emphases on melodic dynamics, it also demonstrates a broadening in Disturbed's musical range compared to the heavy onslaught of their debut album. Believe was the last album to feature Steve "Fuzz" Kmak on bass. Believe is also, to date, the only studio album by Disturbed with a title track that was not released as a single. This was also Disturbed's second consecutive album to feature the Parental Advisory label.
