Gerald and Eddie collaborated many times, recording an album called "Father and Son" together. He also sang with his brother Sean and Marc Gordon in the R&B Trio, LeVert.
Levert was born in Cleveland and was also a part LSG, the R & B supergroup which included platinum selling stars Keith Sweat and Johnny Gill.
Some of Gerald Levert's most popular ballads include "I'd Give Anything to Fall in Love", and "You Got That Love."
