Trey Lorenz was born in 1969 in Florence, South Carolina. He got his start in the music industry as a supporting singer for Mariah Carey during her first tour in 1990. He also provided background vocals on her album Emotions in the following year.
In 1992, Lorenz served as Carey's backing singer in her 1992 appearance on MTV Unplugged. They sang a cover of Jackson 5's 'I'll Be There' together and their duet reached #1 in the United States. Likely as a result of his successful duet with Carey, Lorenz was offered a record deal and recorded his self-titled debut album.
The album scored a successful single with 'Someone To Hold' which reached #5 on the R&B charts and #19 on the Hot 100. However, the follow-up singles 'Photograph Of Mary' and 'Just To Be Close To You' did not perform well and the album did not succeed commercially upon its release.
Dropped from his label, Lorenz continued to do background vocals for a variety of artists including TLC and Usher. He resumed his position with Carey in 1997 and supported her on her albums and tours from thereon. He was signed to Carey's label MonarC and Jermaine Dupri's So So Def Records for a short time but didn't put music out on either label.
In 2006, Lorenz released his second album, Mr. Mista. The album was released while Lorenz was on tour with Carey in her Adventures of Mimi Tour in which Lorenz sings several tracks.
