White was born Barry Eugene Carter in Galveston, Texas on September 12, 1944, and grew up in South Central Los Angeles. White was the older of two children. His brother Darryl was 13 months younger than Barry. He grew up listening to his mother's classical music collection and first took to the piano, emulating what he heard on the records.

In 1972, White got his big break producing a girl group he had discovered called Love Unlimited. Formed in imitative style of the Motown girl group The Supremes, the group members had gradually honed their talents with White for two years previously until they signed contracts with Uni Records. His friend Paul Politi hooked him up with music industry businessman Larry Nunes, who helped to finance their album. After it was recorded, Nunes took the recording to Russ Regan, who was the head of the Uni label owned by MCA. The album, 1972's From A Girl's Point of View We Give to You... Love Unlimited, became a million album seller and the first of White's string of long-titled albums and singles.  White produced, wrote and arranged their classic soul ballad "Walkin' in the Rain with the One I Love", which climbed to #14 in the Billboard Hot 100 Pop chart and #6 on the Billboard R&B chart in late 1972. This single also reached #12 in the UK chart. White's voice can clearly be heard in this piece as he plays the lover who answers the phone call of the female lead.  Soon after, Regan left Uni for 20th Century Records. Without Regan, White's relationship with Uni soured. With his relationship with Uni over and Love Unlimited contract-bound with the label, White was able to switch both his production deal and the group to 20th Century Records. They recorded several other hits throughout the 1970s, "I Belong to You", which spent over five months on the Billboard R&B chart in 1974 including a week at #1 and "Under the Influence of Love", which hit #3 on the Billboard Pop album charts. White married the lead singer of the group, Glodean James, on July 4, 1974.Answer this question using a quote from the following article:
