1985–1992: Formation and early years as Mighty Joe Young

In 1985, Scott Weiland and his friends in their band Soi-Disant — guitarist Corey Hickok and drummer David Allin — first encountered Robert DeLeo playing live at various gigs, deciding to track him down after witnessing his shows. Weiland, DeLeo, Hickok and Allin would eventually form a band called Swing. Allin left after a few years. The remaining members saw drummer Eric Kretz play in a Long Beach club and convinced him to join them. Guitarist Hickok eventually left the band in 1989; in need of a replacement and auditioning many guitarists, Robert suggested his older brother, Dean. At the time, Dean was a successful businessman who had left behind his previous musical career but still played guitar as a hobby. The band managed to convince Dean to play for Swing, completing the original lineup. Shortly afterwards, the band changed its name to Mighty Joe Young. They recorded a demo tape around 1990. The Mighty Joe Young demo features tracks that would go on to be re-recorded for the band's first studio album, as well as some musical styles that would not be featured on any of the band's studio albums, such as funk and yodeling.

1992–1995: Core and Purple

Stone Temple Pilots developed a fan base in San Diego clubs and in 1992 signed with Atlantic Records. Their first album, Core, was released on September 29, 1992, and peaked at No. 3 on the Billboard Albums Chart. Core was a big success, producing hits "Sex Type Thing", "Plush", "Creep", and "Wicked Garden". While the album was a major commercial success, some in the music press criticized the band as "grunge imitators". The same year, Scott Weiland and Dean DeLeo played an acoustic version of "Plush" on the MTV show Headbangers Ball. This is considered one of Weiland's greatest vocal performances. Despite negative reviews from some critics, Stone Temple Pilots continued to gain fans and toured, opening for bands such as Rage Against the Machine and Megadeth. 1993 brought continued success on the road, with the band headlining a two-and-a-half-month American tour.

1995–2003: Tiny Music, No. 4, and Shangri-La Dee Da

In October 1995, the band regrouped to begin recording its third album, renting out a mansion in Santa Barbara, California, for the band to live together during the recording process. Stone Temple Pilots released the album Tiny Music... Songs from the Vatican Gift Shop on March 5, 1996. The album's sound marked a drastic change from their previous outings, oriented more in the direction of glam rock and psychedelic music than that of the hard rock/grunge sound that propelled them to popularity; critical reception, at the time, was mixed. Rolling Stone, a magazine known for its initial dismissal of the band's music, held a favorable opinion of the album, regarding the release as the group's best effort to date. They expressed surprise, however, at "the clattering, upbeat character of the music" given Weiland's much-publicized run-ins with drugs and the law. Stone Temple Pilots were also featured on the cover of issue No. 753 in February 1997.

2003–2008: Separation and members' other projects

Despite reports that the band had begun work on a sixth studio album in 2002, the band went quiet by the end of that year after reports of an altercation between Dean DeLeo and Weiland after the last show of Stone Temple Pilots' fall 2002 tour. As a capstone to the band's career, Atlantic Records released a greatest hits album, Thank You, with a bonus DVD of archive material and music videos, in 2003. Five days after Thank You was released, the DeLeo brothers revealed in an interview with Guitar One that the band was officially done. Following the band's dissolution, Weiland was recruited to join Velvet Revolver—a successful supergroup—where they released two albums, Contraband in 2004 and Libertad in 2007 before breaking up in 2008. Likewise, the DeLeo brothers formed the supergroup Army of Anyone with vocalist Richard Patrick of the industrial rock band Filter and session drummer Ray Luzier. The band released its self-titled album in 2006 before going on "indefinite hiatus" in 2007. Eric Kretz kept a lower profile during this time, operating his own studio, Bomb Shelter Studios, and drumming for the band Spiralarms.

2008–2011: Reunion and self-titled album

According to Dean DeLeo, steps toward a Stone Temple Pilots reformation started with a phone call from Weiland's wife, Mary Forsberg. She invited the DeLeo brothers to play at a private beach party, which led to the reconciliation of Weiland and the DeLeo brothers. In 2007, Dean DeLeo and Weiland discussed a concert promoter's offer to headline several summer festivals. Weiland subsequently left Velvet Revolver in April 2008 and the following month, Stone Temple Pilots announced they were reuniting for a 65-date North American tour. The group officially reunited for a private gig at the Houdini Mansion and held their first public show on Jimmy Kimmel Live! on May 1. Stone Temple Pilots toured throughout the summer and fall, headlining the Virgin Mobile Festival in Baltimore in August of that year as well as the 10th annual Voodoo Experience in New Orleans. The band's six-month reunion tour wrapped up on Halloween 2008 in Pelham, Alabama.

2012–2013: Split with Weiland and legal proceedings

On June 26, 2012, STP released its first-ever concert film, Alive in the Windy City, on DVD and Blu-ray. The performance was filmed at a sold-out show in March 2010 at the Riviera Theatre in Chicago.

2013–2015: Chester Bennington era and Weiland's death

On May 18, 2013, the three remaining members of Stone Temple Pilots performed with Chester Bennington of Linkin Park, appearing as special guests at the 21st Annual KROQ Weenie Roast, and the May 19, 2013 Live 105 BFD festival near San Francisco, where they performed a new song, "Out of Time". On May 19, 2013, STP released a free download of their new single "Out of Time" with Bennington now an official member. Bennington had exclaimed years before in interviews that being in Stone Temple Pilots was his lifelong dream. The new lineup performed again on May 30, 2013, at the MusiCares MAP Fund Benefit Concert in Los Angeles, California, and were joined by Weiland's former bandmates Slash and Duff McKagan on stage to perform "All the Young Dudes".

2016–2018: New singer Jeff Gutt and second self-titled album

In February 2016, Stone Temple Pilots launched an online audition for a new vocalist, stating, "If you think you have what it takes to front this band, record with this band, and tour with this band, we would dig hearing from you."

On July 26, 2017, the band announced that a 25th anniversary edition of Core would be released on September 29, 2017. The reissue includes a 25th Anniversary box set, a remastered version of the album, previously unreleased demos and b-sides, and parts of three live performances from 1993 (Castaic Lake Natural Amphitheater, Reading Festival, and MTV Unplugged). In October 2017, Dean DeLeo said that the band's search for a new vocalist was "going great", and that the band is "working on new material". On November 14, the band revealed that Jeff Gutt had been chosen as their new lead singer. On November 15, 2017, the band released the song, "Meadow". On January 31, 2018, the band released a second single, "Roll Me Under", and announced the release date of the album. The band's second self-titled album was released on March 16, 2018. In mid-2018, the band embarked on a co-headlining tour with Bush and the Cult.

2019–present: Perdida and continued touring with Gutt

On October 4, 2019, Eric Kretz told Loudwire that a new album was complete and includes a flute solo. On December 2, the band announced that their eighth studio album, Perdida, would be released on February 7, 2020, and would be "an acoustic record largely recorded on vintage instruments". They continued to tour throughout the 2020s and co-headlined a summer U.S. tour with the band Live in 2024.

Legacy

Core, certified 8× platinum by the RIAA, drove the band to popularity. Stone Temple Pilots went on to become one of the most commercially successful rock bands of the 1990s, selling 40 million records worldwide, including 17.5 million units in the United States, before their dissolution in 2003. The band has had 16 top ten singles on the Billboard rock charts, eight of which peaked at No. 1, and one No. 1 album for Purple in 1994. That same year, the band won a Grammy for "Best Hard Rock Performance" for the song "Plush" from the album Core. Stone Temple Pilots were also ranked No. 40 on VH1's The 100 Greatest Artists of Hard Rock.
