David Foster is among the most successful producers and composers in all of music, lending his signature aesthetic to smash hits by Celine Dion, Chicago and Whitney Houston, among others. In the process, he virtually defined the adult contemporary format. In 1979, he earned his first Grammy for penning Earth, Wind and Fire's "After the Love Has Gone." From there, Foster's career exploded. He composed and produced Chicago's hit "Hard to Say I'm Sorry," followed by Lionel Richie's "Can't Slow Down." With 1984's Chicago 17, Foster scored the smash single "Hard Habit to Break." A year later, Foster wrote and produced John Parr's "St. Elmo's Fire," and in 1986, he reunited with Chicago for their 18th LP and also with the Peter Cetera, for whom he wrote the chart-topping "The Glory of Love." In 1990, Foster began his collaboration with Celine Dion, generating the hit "Have a Heart." A year later, he teamed with Natalie Cole for her mega-hit Unforgettable, winning three more Grammys. In 1992, Foster collaborated with Whitney Houston on "The Bodyguard," which netted him another Album of the Year Grammy. For Dion, he next produced 1993's The Colour of My Love, which spawned the smash "The Power of Love." With Dion's 1996 Falling Into You, Foster again took home the Album of the Year Grammy. In 2011, Foster released Hit Man Returns: David Foster and Friends. Foster continues to tour.
