The "Soul Glo" song from "Coming to America" is sung by Christopher Max. Nile Rodgers, the producer of the movie soundtrack, was Max's producer at the time and due to Max's remarkable ability to sing high notes, Rodgers realized Max was the right man for the job.
Max was an unknown singer at the time. He had studied for a year at the Berklee College of Music in Boston. During that time, he learned how to play drums, piano, electric bass, and electric and acoustic guitar. He formed a band called Carerra at first, then World Citizenz. After the band's break-up, he worked with Rodgers, who helped him land his best-known job: singing the "Soul Glo" song. As of 2015, Max lives in the Netherlands, where he is still an active musician.
