Also associated with the group was Coolio's younger brother [a=P.S. Pookie] and OG Los Angeles Rapper, Mad CJ Mac.

Legendary Hip Hop Producer and DJ Sir Jinx and Lench Mob DJ Chilly Chill were the main producers for the group. With Toones on co-production and cuts, WC and Ice Cube chose some of the samples used on the first album. The album also featured guest appearances by [a=J. Dee] of the Lench Mob, MC Eiht of Compton's Most Wanted, and a fictional character named "Granny"-who poses as WC and Crazy Toone's grandmother in skits throughout both albums and [a=DJ Crazy Toones]'s 1996 mixtape, "That Nigga's Crazy: Presents MAAD Circle Underground".
On their sophmore release, "Curb Servin", Crazy Toones took most of the production responsibilities.

Film director F. Gary Gray ("Straight Outta Compton") can be seen acting in MAAD Circle's music video "Dress Code".
Their music video "Ain't A Damn Thing Changed" features guest appearances by Cypress Hill, Ice Cube, and [a=Boo-Yaa T.r.i.b.e.].

The group was given homage by Compton rapper Kendrick Lamar on his debut album titled "Good Kid, M.A.A.D. City".
