Which group did Beyoncé lead before launching her solo career?

Beyoncé led Destiny's Child before launching her solo career. The Houston-born group became one of the best-selling female groups in music history, with Beyoncé serving as its lead vocalist during its most successful years.

Destiny's Child developed from a Houston vocal group called Girl's Tyme, which competed on the television program Star Search in 1993. The lineup changed several times before the group signed with Columbia Records and released its self-titled debut album in 1998.

The best-known final lineup consisted of Beyoncé Knowles, Kelly Rowland, and Michelle Williams. Their hits included “Bills, Bills, Bills,” “Say My Name,” “Survivor,” and “Bootylicious.” “Say My Name” won two Grammy Awards in 2001 and became one of the group's signature recordings.

Destiny's Child announced a temporary hiatus in 2001, reunited for further work, and formally disbanded after the release of their compilation album Number 1's in 2005. Beyoncé began releasing solo music while still connected to the group, including her debut album Dangerously in Love in 2003.
