In the late-1980s, Oakland-based production and songwriting duo Denzil Foster and Thomas McElroy first conceived the idea of a modern-day girl group in the tradition of The Supremes, Martha and the Vandellas, The Ronettes and other commercially successful female bands which had flourished in the late 1950s and early 1960s when they were assembling their 1988 compilation project FM2 for Atlantic Records. Foster and McElroy envisioned an entertainment unit with interchangeable but not identical parts in which every member would qualify to take the lead on any given number. Thus, their plan was to recruit singers who possessed strong voices, noticeably good looks, and intelligence. Approximately 3000 women attended the auditions held in 1988, with Dawn Robinson, Cindy Herron, and Maxine Jones making the final cut. Originally conceived as a trio, Foster and McElroy decided to create a quartet after hearing Terry Ellis audition whose plane had been late from Houston, Texas. At first, they selected the band name 4-U but soon shifted to Vogue, ultimately settling on En Vogue, upon learning that another group had already claimed the Vogue moniker.  After forming, the group began working with their producers on their debut album. Recording began in August 1989 and wrapped up in December of the same year. Born to Sing was released on April 3, 1990. The album peaked at No. 21 on the Billboard 200 chart and No. 3 on Billboard's R&B Albums Chart. The first single, "Hold On," was released to radio in late February 1990 and became a crossover pop hit, reaching No. 2 on the Billboard Hot 100 singles chart, and No. 1 on both the R&B singles and Hot Dance Music/Club Play charts. It later went to No. 5 in the UK, and became a hit in Europe. The next two singles, "Lies" and "You Don't Have to Worry," each went to No. 1 on the Billboard R&B charts, while the fourth and final single, "Don't Go," charted at No. 3 on the Billboard R&B. The album was later certified triple platinum by the RIAA.  "Hold On" was awarded a Billboard Music Award for "#1 R&B Single of the Year," a Soul Train Award for "R&B/Urban Contemporary Single of the Year, Group, Band or Duo" and have been nominated for a Grammy Award for Best R&B Vocal Performance by a Duo or Group. In 1990, En Vogue signed an endorsement deal to appear in a Diet Coke commercial directed by Spike Lee.
