Known particularly for his cover art for the albums of such artists and bands as Ice-T and Body Count, this graphic artist and graffiti designer also created publicity and promotional products for the Fox television series Married... with Children.
Early in his career, he worked as a designer for Warner Brothers Records; later, he created album art for Rhyme $yndicate Records and other independent labels. He was the original merchandiser for No Doubt from 1988 until around 2006.
Ice-T donated some of his reproductions and tour apparel to the Smithsonian's National Portrait gallery. Both the Body Count track "Cop Killer" and Halili's cover art for the album that included it resulted in a great deal of controversy.
Born in Fullerton, California, he later opened a design studio in Orange County.
He belongs to The Universal Zulu Nation, a hip hop music promotional organization founded by DJ Afrika Bambaataa. He became good friends with Eric and Gwen Stefani during his days working with No Doubt.
