Background: Expose is an American Latin freestyle vocal group. Primarily consisting of lead vocalists Jeanette Jurado, Ann Curless, and Gioia Bruno, the group achieved much of their success between 1984 and 1993, becoming the first group to have four top ten hits on the Billboard Hot 100 chart from its debut album, including the 1988 #1 hit "Seasons Change". In March 2015, Billboard magazine named the group the eighth most-successful girl group of all-time. The group was popular in dance clubs, mainstream Top 40 and adult contemporary charts in the United States.
Context: In March 1987, the new lineup of Expose released its debut album Exposure on Arista Records, led by the pop/dance hit "Come Go with Me" which reached #5 on the US Billboard Hot 100 chart. During the summer of 1987, a re-recorded version of "Point of No Return" was released, with Jurado now performing lead vocals, and it too topped out at #5 on the US Hot 100. While the initial distribution of Exposure to suppliers contained the original 1984 version of that song, subsequent pressings contained the new version. "Let Me Be the One", a mid-tempo R&B song with Bruno on lead vocal, became yet another hit reaching #7 on the US Hot 100 and also garnering significant R&B radio airplay. The group's highest charting hit occurred in February 1988 with the #1 US hit ballad "Seasons Change". Along with that came a Soul Train Award nomination for Best New Artist; television appearances on American Bandstand, Solid Gold, Showtime at the Apollo, and The Late Show Starring Joan Rivers; and the group was tapped to be the opening act for Lisa Lisa and Cult Jam during its national tour.  Expose also performed backing vocals on Kashif's 1987 Arista/BMG Records album Love Changes, on the song "Who's Getting Serious?".  During Expose's peak, the group endured legal issues behind the scenes. The members had a restrictive contract and there were reports in the media of backstage battles. According to Bruno, they were only paid $200 per show. Reportedly, the record label had to intervene to try to keep the peace between the members and their producers. Despite this intervention, the members filed a lawsuit and ultimately settled their legal case for a renegotiated contract.
