The On & On singer has partnered up with event management company The Right Productions to raise money for Michigan Women's Foundation campaign and Enough SAID (Enough Sexual Assault in Detroit), which aim to test more than 11,000 abandoned rape kits found in the Detroit Police Department's storage in 2009, according to RollingStone.com.

The singer will give $5 (GBP3.80) from each ticket sold for the 12 August (16) show at Detroit's Chene Park Amphitheater, proceeds from a $100 (GBP75)-per-ticket reception, and a $1,000 (GBP755)-per-person VIP reception to help pay for the $490 (GBP370) tests.

"It should come as no surprise that an artist with Erykah Badu's impressive history of social consciousness would join forces with the black women leaders of Detroit to address this important social issue," a statement from Kim Trent, president of the 490 Challenge reads. "We are very excited that she is lending her considerable talent to our cause."
