Boy Krazy was put together through auditions by a management company in New York. The group featured female singers Kimberly Blake, Josselyne Jones, Johnna Lee Cummings, Renée Veneziale, and Ruth Ann Roberts (a former Miss Junior America).
Their signature pop song "That's What Love Can Do", written and produced by British mega music trio Stock Aitken Waterman, was released in 1991, but it failed to become a hit. Shortly after the release of the single, Veneziale left the band.
Carrying on as a foursome, the group released their second single "All You Have to Do" in 1992, but it also failed to chart. That same year, "That's What Love Can Do" started gaining success in clubs and discothèques across America and substantial airplay on radio stations. The song was remixed and re-released, becoming a hit in the US where it peaked at #18 on the Billboard Hot 100 in March 1993. It also reached #1 in pop airplay on the Radio & Records CHR/Pop chart. In the liner notes from their self-titled album the group credited KQKS/Denver, Colorado, for breaking the latter after one of the staffers played a remixed version of the track in December 1992.
The album Boy Krazy was released in 1993, and also included the follow-up single "Good Times with Bad Boys", which also hit the Billboard Hot 100. Each member sings the lead vocals on at least two songs on the album.
Main lead singer Cummings left the band in late 1993. The remaining members tried to develop a new album unsuccessfully and the group split shortly after. Additionally, they were supposed to release "Love Is a Freaky Thing" as their fourth single, but it was never released.
