"No. 4" is the fourth studio album of the American rock band Stone Temple Pilots. Released on October 26, 1999, by Atlantic Records, the album hit the music industry not only with its rock and hard rock features but also carried aspects of blues and psychedelic rock. Although it underwent a bit of a turbulent creation due to the band members' personal issues, particularly with lead singer Scott Weiland's drug addiction, it still managed to reach a commercial success.
Interestingly, while the album was initially untitled, it was casually referred to as "No. 4" in reference to it being the band's fourth album, and the nickname became so popular that it ended up being the official title. Unique to the "No. 4" album are its single releases, with "Down" and "Sour Girl" both having fared well on the charts; the former even won a Grammy for Best Hard Rock Performance in 2000.
The album, often defined by its raw energy and acoustic elements, successfully demonstrated the band's versatility and growth since their debut in 1992. Although it received mixed reviews from critics, it managed to secure a no. 6 spot on the Billboard 200 chart and has sold over a million copies in the United States alone, proving itself a significant part of Stone Temple Pilots' discography.
