The Police are a three-piece rock ban consisting of Sting (vocals, bass guitar), Andy Summers (guitar, vocals) and Stewart Copeland (drums, percussion, vocals). The band became globally popular in the early 1980s, playing a style of rock that was influenced by jazz, rock and reggae music. Their 1983 album, Synchronicity, was number one in the UK and the US and sold over 8,000,000 copies in the US. The band broke up in the mid-1980s, but reunited in early 2007 with the announcement that they were undertaking a world tour. The tour was scheduled from the middle of that year on until mid-2008, in celebration of the 30th anniversary of their hit single "Roxanne" and also, to a lesser extent, that of their formation as a group. To date The Police have sold over 50 million albums worldwide. Rolling Stone ranked The Police number 70 on their list of the 100 Greatest Artists of All Time.
