The Police were an English rock band formed in London in 1977. Within a few months of their first gig, the line-up settled as Sting, Andy Summers (guitar) and Stewart Copeland, and remained unchanged for the rest of the band's history. The Police became globally popular in the late 1970s and early to mid 1980s. Emerging in the British new wave scene, they played a style of rock influenced by punk, reggae, and jazz.
