Destiny's Child

Context: In 1990, Beyonce Knowles met rapper LaTavia Roberson while auditioning for a girl group. Based in Houston, Texas, they were joined to a group that performed rapping and dancing. Kelly Rowland, who relocated to Knowles' house because of family issues, joined them in 1992. Originally named Girl's Tyme, they were eventually cut down to six members including Tamar Davis and sisters Nikki and Nina Taylor. With Knowles and Rowland, Girl's Tyme attracted nationwide attention: west-coast R&B producer Arne Frager flew to Houston to see them. He brought them to his studio, The Plant Recording Studios, in Northern California, with focus on Knowles' vocals because Frager thought she had personality and the ability to sing. With efforts to sign Girl's Tyme to a major record deal, Frager's strategy was to debut the group in Star Search, the biggest talent show on national TV at the time. However, they lost the competition because, according to Knowles, their choice of song was wrong; they were actually rapping instead of singing.  Because of the group's defeat, Knowles' father, Mathew, voluntarily dedicated his time to manage them. Mathew Knowles decided to cut the original lineup to four, with the removal of Davis and the Taylor sisters and the inclusion of LeToya Luckett in 1993. Aside from spending time at their church in Houston, Girl's Tyme practiced in their backyards and at Headliners Salon, owned by Knowles' mother, Tina. The group would test routines in the salon, when it was on Montrose Boulevard in Houston, and sometimes would collect tips from the customers. Their try out would be critiqued by the people inside. During their school days, Girl's Tyme performed at local gigs. When summer came, Mathew Knowles established a "boot camp" to train them in dance and vocal lessons. After rigorous training, they began performing as opening acts for established R&B groups of that time such as SWV, Dru Hill and Immature. Tina Knowles designed the group's attire for their performances.  Over the course of the early years in their career, Girl's Tyme changed their name to Something Fresh, Cliche, the Dolls, and to Destiny. The group signed with Elektra Records with the name Destiny, but were dropped several months later before they could release an album. The pursuit of a record deal affected the Knowles family: in 1995, Mathew Knowles resigned from his job as a medical-equipment salesman, a move that reduced Knowles' family's income by half, and her parents briefly separated due to the pressure. In 1996, they changed their name to Destiny's Child, which was taken from a passage in the Book of Isaiah. Mathew Knowles helped in negotiating a record deal with Columbia Records, which signed the group that same year. Prior to signing with Columbia, the group had recorded several tracks in Oakland, California produced by D'wayne Wiggins of Tony! Toni! Tone!, including "Killing Time", which upon the label's recognition that Destiny's Child had a "unique quality", was included in the soundtrack to the 1997 film Men in Black. CANNOTANSWER
