Sunday morning, in the wake of the flood of activists and activated citizens that filled the streets of Los Angeles on this first anniversary of the Women’s March, KCRW DJ Anne Litt played a heretofore unknown to us song that seemed fittingly excellent; we felt the need to share.

The 1976 song—”Cashing In”—was written by Taiwo and Kehinde Lijadu, two Nigerian sisters who pushed the envelope, both musically and lyrically, tackling issues that were beyond progressive for their time, especially in 1970s Nigeria.

You can follow the Lijadu sisters, who have an actively run Facebook page, and explore their catalog via iTunes + order physical and digital releases through Knitting Factory Records.
