The Police were a British rock band formed in London in 1977. For most of their history the band consisted of Sting (lead vocals, bass guitar, primary songwriter), Andy Summers (guitar) and Stewart Copeland (drums, percussion). The Police became globally popular in the late 1970s and early 1980s and are generally regarded as one of the first new-wave groups to achieve mainstream success, playing a style of rock influenced by punk, reggae, and jazz. They are also considered one of the leaders of the Second British Invasion of the United States.

Each band member continued with his solo career over the next 20 years. Sting continued recording and touring as a solo performer to great success. Summers recorded a number of albums, both as a solo artist and in collaboration with other musicians. Copeland became a prolific producer of movie and television soundtracks, and he recorded and toured with two new bands, Animal Logic and Oysterhead. However, a few events did bring the Police back together, albeit briefly. Summers played guitar on Sting's album ...Nothing Like the Sun (1987), a favour the singer returned by playing bass on Summers' album Charming Snakes (1989) and later singing lead vocals on "'Round Midnight" for Summers' tribute to Thelonious Monk Green Chimneys (1999). On 2 October 1991 (Sting's 40th birthday), Summers joined Sting on stage at the Hollywood Bowl during The Soul Cages Tour to perform "Walking on the Moon", "Every Breath You Take", and "Message in a Bottle". The performance was broadcast as a pay-per-view event.  On 22 August 1992, Sting married Trudie Styler in an 11th-century chapel in Wiltshire, southwest England. Summers and Copeland were invited to the ceremony and reception. Aware that all band members were present, the wedding guests pressured the trio into playing, and they performed "Roxanne" and "Message in a Bottle". Copeland said later that "after about three minutes, it became 'the thing' again". In 1995 A&M released Live!, a double live album produced by Andy Summers featuring two complete concerts--one recorded on 27 November 1979 at the Orpheum Theatre in Boston during the Reggatta de Blanc tour, and one recorded on 2 November 1983 at the Omni in Atlanta, Georgia during the Synchronicity Tour (the latter one was also documented in the VHS tape Synchronicity Concert in 1984).  On 10 March 2003, the Police were inducted into the Rock and Roll Hall of Fame and performed "Roxanne", "Message in a Bottle", and "Every Breath You Take" live, as a group (the last song was performed alongside Steven Tyler, Gwen Stefani, and John Mayer). In the autumn of 2003, Sting released his autobiography, Broken Music.  In 2004, Copeland and Summers joined Incubus onstage at KROQ's Almost Acoustic Christmas concert in Los Angeles performing "Roxanne" and "Message in a Bottle". In 2004, Henry Padovani released an album with the participation of Copeland and Sting on one track, reuniting the original Police line-up for the first time since 1977. Also in 2004, Rolling Stone ranked The Police No. 70 on their list of the 100 Greatest Artists of All Time.  In 2006, Stewart Copeland made a rockumentary about the band called Everyone Stares: The Police Inside Out, based on Super-8 filming he did when the band was touring and recording in the late 1970s and early 1980s. In October 2006, Andy Summers released One Train Later, an autobiographical memoir detailing his early career and time with the band.
