Immature, also known as Imx, are an R&B group that hail out of Los Angles, California. The group consists of Marques “Batman” Houston (born August 4, 1981), Jerome “Romeo” Jones (born October 25, 1981), and Kelton “LDB” Kessee (born January 2, 1981). The group has released four albums under the name Immature: “On Our Worst Behavior” (1992); “Playtyme Is Over” (1994); “We Got It” (1995); and “The Journey” (1997). 1999 saw a name change for the group to Imx and the release of “Introducing Imx,” followed by “Imx.” A Greatest Hits album appeared in 2001. The group disbanded in 2002 but came together in 2010 to record a new album.

The band initially came together when Houston, Jones and Don “Half-Pint” Santos decided to form a band while they were still teenagers of just thirteen. Santos was eventually replaced by Kelton Kessee in 1993, who has remained a full-time member since then. The group's debut, “On Our Worst Behavior,” arrived in 1992 and spawned the singles “Da Munchies,” “I Wanna Know U That Way” and “Tear It Up (On Our Worst Behavior).” Despite the album failing to chart, the single, “Tear It Up (On Our Worst Behavior)” peaked at #39 on Billboard's Hot R&B/Hip-Hop Songs Charts, and gained the group some mainstream attention. The group's second offering, “Playtyme Is Over” fared better in 1994, peaking at #88 on the Billboard Hot 200 Charts, and #26 on Billboard's Top R&B/Hip-Hop Albums. Immature put out two more albums, gaining more fans along the way as their popularity slowly began to grow.

As Imx, the group released their fifth album, “Introducing Imx,” which produced the popular singles: “Stay the Night,” “Keep It On the Low” and “In & Out of Love.” By the time Imx released their sixth, and final, album, “Imx” in 2001, the group were still not breaking through to mainstream audiences and charting low on the Billboard charts, as a result the group decided to part ways and focus on side projects, such as scoring soundtracks for feature films. Houston and Jones began solo careers, with Kessee going on to work as a record producer. Houston debuted his solo album, “MH,” in 2003, with Jones releasing his in 2004; “Food for Thought.” Houston went on to release four more solo albums and pursue an acting career alongside Jones, both starred in “You Got Served” (2004). All three former members of Imx are still active in the music and film industry.
