With 10 multi-platinum albums and 16 Top 30 hits, Gramm first surfaced as the drummer with the band Black Sheep, assuming lead vocal duties prior to recording the group's self-titled 1975 Capitol debut. The recordings captured the attention of journeyman guitarist Mick Jones, and Jones soon tapped Gramm for his new group. Gramm's powerfully distinctive vocals were inescapable in the years to follow as Foreigner reeled off an impressive series of pop radio hits, including "Hot Blooded," "Double Vision," "Urgent," and "Waiting for a Girl Like You." The hits culminated in 1984's chart-topping power ballad "I Want to Know What Love Is," which became a number one hit. After rising to prominence as the frontman for the hard rock combo Foreigner, Lou mounted a successful solo career during the '80s, cracking the Top 10 in 1987 with the single "Midnight Blue" and repeating the process two years later with "Just Between You and Me."
