Foreigner released their fourth album simply called Foreigner 4 in late June of 1981. The album was the band's first since 1979's Platinum seller Head Games. Head Games while a Platinum seller, did not sell as well as the first two albums and founding members Al Greenwood and Ian McDonald quit over creative and personal differences. Instead of breaking up,lead singer Lou Gramm, guitarist Mick Jones, drummer Dennis Elliot and bass player Rick Wills forged ahead with Mick and AC/DC and Def Leppard producer now Shania Twain's husband Mutt Lange co-producing and unleashed Foreigner's most successful album ever with Foreigner 4. The album was #1 for ten straight weeks and sold millions thanks to the massive Top 5 hits Urgent(with Jr Walker's sax solo) and the ballad Waiting For a Girl Like You. Also, the album contained rock radio classics like Juke Box Hero, I'm Gonna Win and the opening Night Life. My personal faves are Girl on the Moon and the closing Don't Let Go. To correct a one star reviewer, Foreigner continue to be heard on rock radio whilst Duran Duran were nothing but a bunch of Roxy Music poseurs. Foreigner lost popularity when Lou Gramm quit but Duran Duran lost popularity because their music was too tired and contrived and dated. I recommend Foreigner 4.
