Foreigner is a British-American rock band formed in New York City in 1976 by veteran English musicians Mick Jones, ex-King Crimson member Ian McDonald, and a then-unknown American vocalist Lou Gramm (Louis Grammatico). Foreigner has sold more than 50 million albums worldwide  (including over 37.5 million in the United States alone).
The band is led by British journeyman rocker Mick Jones (former member of Nero and the Gladiators, Spooky Tooth, and The Leslie West Band) who in early 1976 met with ex-King Crimson member Ian McDonald in NYC and formed Foreigner with Lou Gramm (ex-Black Sheep), Dennis Elliott, Al Greenwood, and Ed Gagliardi as a sextet. Jones came up with the name from the fact that he, McDonald, and Elliott were British, while Gramm, Greenwood, and Gagliardi were Americans. 
The band's debut album Foreigner was released in March 1977 and sold more than four million copies in the United States, staying in the Top 20 for a year with such hits as "Feels Like the First Time," "Cold as Ice" and "Long Long Way From Home." Their second album, Double Vision (released in June 1978), topped their previous selling five million records and spawned "Hot Blooded," the title track "Double Vision" and "Blue Morning Blue Day." Their third album, Head Games, which was referred to by Gramm as their "grainiest" album, was also successful due to the thunderous "Dirty White Boy" and another title track hit "Head Games".
For 1979's Head Games, bassist Ed Gagliardi was replaced by Englishman Rick Wills. In September 1980, keyboardist Al Greenwood and co-founder Ian McDonald were sacked as Jones wished to have more control over the band and write most of the music (along with Gramm). The band was now stripped down to a quartet, with session players brought in as needed to record or tour (see below for complete list of members). Greenwood soon joined Gagliardi to form the AOR band SPYS with John Blanco, Billy Milne, and John DiGaudio. The band released two albums, a self-titled debut, and the follow-up Behind Enemy Lines.
