Donald “DJ Duck” Harris and Donald “Papa Don” Birks get off the Muni bus near 24th and Mission streets in San Francisco, Calif. Papa Don and DJ Duck are independent hip-hop rappers and producers paying their way by “hustling” their records on the streets and on the Internet. “I don’t care about nothing else, as long as I can do shows and get paid,” Papa Don said. Papa Don got his stage name from a nickname his aunt calls him.
