1996-98: Formation

The girls of One Voice met while they were in elementary school. They originally started out as a quintet, which at the time included Aimee Castillo (no relation to Monica), and another original member named Lindsay Mangoba, but before anything was recorded she later left the group and was replaced by Melissa Ruiz. The girls eventually landed a record deal with Kamikaze Records (an independent label) in 1998, and contracted the talent of producer James Earley.

1999-2000: Just The Beginning

Original Line-up (2000) Clockwise from Bottom left: Marie Ceralvo, Mae Ceralvo, Monica Castillo, Melissa Ruiz, and Aimee Castillo.

Recording their debut album was tough. The girls wanted it to be just right and they had to make up their minds about what kind of album they wanted to record. First they hired the right producer, multi-platinum producer James "Jae-E" Earley, who wrote and/or produced the majority of the first album. Then, they chose an urban-pop/OPM sound. The group released their first single "All Day All Nite" in October of 1998, it failed to chart. The group released their debut album Just the Beginning on April 20, 1999.

Their second single "When U Think About Me" was released to radio stations across the United States and it became their most successful single to date. It peaked at #17 on the US Rhythmic Top 40 chart and #96 on the Hot R&B/Hip-Hop Songs chart. The song was also featured in an original MTV movie called Jailbait. The song was covered by singer Billy Crawford in 2002, where it became a hit in Europe. Due to the success of "When U Think About Me", their album was re-released a year later. The album sold 100,000 copies worldwide and it was certified gold. Two more singles were released from their debut album "Boyfriend", and "Never Leave Your Side", however both songs failed to chart.

2001-02: Lineup change and Sincerely Yours

When promotion on Just The Beginning was over, the girls were ready to record their second album. They knew that they would have to show their growth. During this time, Aimee had left the group. The group was hurt by her departure. Even though she left the group, they remained close friends. The group began the recording process of their second album without Aimee. It took another two years but Sincerely Yours was released on June 26, 2001.

It was not as successful as their debut album. The album only sold 45,000 copies worldwide and reviews of the album were mixed. Only two singles were released from the album, but both "Swing Your Love 2 Me" and "So Badd" failed to chart. The girls left the Kamikaze label the following year.

2003-05: Luvin' You and disbandment

Quartet Line-up (2004): Mae, Melissa, Monica & Marie.

The girls took a little break off to live life. They signed with another independent label, Straight Hits Entertainment. Before the release of their third album, they released a self-titled EP giving fans a sneak peek of their upcoming album. Their third album, Luvin' You, was eventually released on January 27, 2004. It became their most successful album to date, selling 150,000 copies worldwide.

Despite being their most successful album, no singles have been released from the album. The group would split in 2005.
