IMx

Immature (later known as IMx) is an American R&B boy band, managed by record producer Chris Stokes. Its members include Marques "Batman" Houston (born August 4, 1981), Jerome "Romeo" Jones (born October 25, 1981), and Kelton "LDB" Kessee (born January 2, 1981), all natives of Los Angeles, where the group was formed. The group released four albums under the Immature moniker: On Our Worst Behavior (1992; the only album to include original member Don "Half Pint" Santos, later replaced by Kessee), Playtyme Is Over (1994), We Got It (1995) and The Journey (1997).

In 1999, the group changed its name to IMx, marking ten years of being a group and released two studio albums Introducing IMx and IMx, as well as a Greatest Hits album in 2001. The group also branched out into film (such as House Party 3 and House Party 4: Down to the Last Minute) and television (such as A Different World, Sister, Sister, Family Matters, Soul Train and All That) before disbanding in 2002.
