The Seven 7A3, commonly known as 7A3, was an American hip-hop group from the late 1980s, notable for its members Brett and Sean Bouldin and DJ Muggs. Their style was characterized by politically charged lyrics and West Coast hip-hop sounds, setting the stage for future groups like Cypress Hill, where DJ Muggs later found significant success. Their debut album, "Coolin' in Cali," released in 1987, featured the hit single "Mad Mad World," marking their brief but influential stint in the music industry. Their contribution to socially-conscious rap music remains significant in the genre's history.
