415 was a rap/hip hop group that formed in Oakland, California in 1988. The group was composed of rappers Richie Rich and D-Loc, and producers DJ Daryl and J.E.D. The group takes its name from the telephone area code 415, which originally served San Francisco and Oakland; it has since split in 1992 with San Francisco retaining 415 while Oakland became served by the new area code 510. But the second album, Nu Niggaz on Tha Blokkk, was not with Richie Rich because he was imprisoned.
