"Women can't rap" used to be the common criticism of females heard back in the day. Interestingly, these days the ratio of female rap fans has grown, yet the number of female rap artists has not grown proportionately.
To answer these questions, which have always puzzled me, I asked a few women who have been in the business for a while: CMG and Special One of the longtime Oakland female duo The Conscious Daughters, and Monica Lynch, the president of Tommy Boy Records during the years 1981 - 1998 where she was instrumental in launching the careers of such artists as Afrika Bambaataa, De La Soul, Digital Underground, House of Pain, Naughty By Nature, and Queen Latifah. She still works closely with Queen Latifah, helping guide the artist, actor, investor, product spokesperson's with her music-related endeavors.
"When you look at rap as a subset of the hip-hop culture at large, you see that a vast vast majority of the DJs were male, a vast majority of the graffiti artists were guys, the vast majority of the breakdance crews were men, and the vast majority of the rappers were male. So it was just an extension of the origins of hip-hop culture being a predominantly male cuture," said the former Tommy Boy president, who firsthand witnessed rap music morph from supposed "fad" into an unstoppable global cultural movement.
