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.
During the recording of the group's first studio album Exposure, the personnel of the group changed. Reports vary based on the source. According to People magazine, one of the original singers quit while two of the girls were fired midway through the recording of the first album, but according to Billboard, all three were fired. Arista records felt that the three original singers lacked star potential. Martinee states that he made the decision himself to replace the three girls, while Miller maintains it was all their choice, and Jurado confirms that Lorenzo wanted to leave. Shortly thereafter, Casanas pursued a solo career and Lorenzo pursued other ambitions; they were replaced by Jeanette Jurado and Gioia Bruno. Miller began a solo career; she was replaced by Ann Curless. Lorenzo returned to the dance charts with the Vendetta Records releases "I Wanna Know" in 1988, and "Stop Me if I Fall in Love" in 1990, while Laurie Miller released the 12" single "Parallels" on Atlantic Records and a second single "Love is a Natural Magical Thing" on Meet Me In Miami Records. Laurie evolved into a headline performer frequently showcasing her talents on cruises with a more intimate jazz style, and formed her own entertainment company called Xica productions. Casanas later resurfaced as a solo artist (Sandee) and released a solo album, Only Time Will Tell, which garnered the club hits "You're The One", "Love Desire", and the Clivilles & Cole-produced bassline-heavy hit "Notice Me". She continued to tour actively in dance clubs and freestyle shows, until her death on December 15, 2008, of a seizure at the age of 46. All three original members: Casanas, Lorenzo and Miller later contributed vocals on songs on the Miami group Will to Power's eponymous 1988 debut album. Gioia Bruno also provided lead vocals on Will to Power's 2004 album, Spirit Warrior.

Alison Maria Krauss was born in Decatur, Illinois, to Fred and Louise Krauss. Her father was a German immigrant who came to the United States in 1952 and taught his native language. Her mother, of German and Italian descent, is the daughter of artists. Krauss grew up in the college town of Champaign, home to the University of Illinois at Urbana-Champaign.
Krauss' second Union Station album Every Time You Say Goodbye was released in 1992, and she went on to win her second Grammy Award for Best Bluegrass Album of the year. She then joined the Grand Ole Opry in 1993 at the age of 21. She was the youngest cast member at the time, and the first bluegrass artist to join the Opry in twenty-nine years. She also collaborated on a project with the Cox Family in 1994, a bluegrass album called I Know Who Holds Tomorrow. Mandolin and guitar player Dan Tyminski replaced Tim Stafford in Union Station in 1994. Late in the year, Krauss recorded with the band Shenandoah on its single "Somewhere in the Vicinity of the Heart", which brought her to the country music Top Ten for the first time and it won the Grammy Award for Best Country Collaboration with Vocals. Also in 1994, Krauss collaborated with Suzy Bogguss, Kathy Mattea, and Crosby, Stills, and Nash to contribute "Teach Your Children" to the AIDS benefit album Red Hot + Country produced by the Red Hot Organization. In 1997, she recorded vocals and violin for "Half a Mind", on Tommy Shaw's 7 Deadly Zens album. Now That I've Found You: A Collection, a compilation of older releases and some covers of her favorite works by other artists, was released in 1995. Some of these covers include Bad Company's "Oh Atlanta", The Foundations' & Dan Schafer's "Baby, Now That I've Found You", which was used in the Australian hit comedy movie The Castle, and The Beatles' "I Will". A cover of Keith Whitley's "When You Say Nothing at All" reached number three on the Billboard country chart; the album peaked in the top fifteen on the all-genre Billboard 200 chart, and sold two million copies to become Krauss' first double-platinum album. Krauss also was nominated for four Country Music Association Awards and won all of them. So Long So Wrong, another Union Station album, was released in 1997 and won the Grammy Award for Best Bluegrass Album. One critic said its sound was "rather untraditional" and "likely [to] change quite a few ... minds about bluegrass." Included on the album is the track "It Doesn't Matter", which was featured in the second-season premiere episode of Buffy the Vampire Slayer and was included on the Buffy soundtrack in 1999. Her next solo release in 1999, Forget About It, included one of her two tracks to appear on the Billboard adult contemporary chart, "Stay". The album was certified gold and charted within the top seventy-five of the Billboard 200 and in the top five of the country chart. In addition, the track "That Kind of Love" was included in another episode of Buffy the Vampire Slayer.
