Biography
Immature was formed in Los Angeles, California in 1992 by Marques "Batman" Houston, Jerome "Romeo" Jones and Don "Half-Pint" Santos. Kelton "LDB" Kessee (the group's drummer) joined the group in 1993 replacing Santos due to his parents pulling him from the group. In 1999 the group would change their name to IMx, feeling Immature no longer reflected the band.
