Madlib (Mind Altering Demented Lessons In Beats) (born Otis Jackson Jr. on October 24, 1973 in Oxnard, California, United States) is a California-based DJ, multi-instrumentalist, rapper, and music producer. Known under a plethora of pseudonyms, he is one of the most prolific and critically acclaimed hip hop producers of the 2000s and has collaborated with a myriad of hip hop artists, including The Alkaholiks, Mos Def, De La Soul, Ghostface Killah, Talib Kweli, A.G., MF DOOM (as Madvillain), and the late J Dilla (as Jaylib). Madlib has described himself as a "DJ first, producer second, and MC last," and he has done several projects as a DJ, mixer, or remixer. Madlib has been an influence on an upcoming generation of producers and musicians, many of which prefer Madlib's abstract styles.
