Betty Wright has passed away at the age of 66. The 70s music icon invested her vocals into R&B and soul. Wright’s niece shared the shocking news via Twitter on Mother’s Day (May 10).

Playing a major role in the music industry, Wright’s most popular songs included “No Pain, (No Gain)” and “Tonight Is the Night.” Her 1972 single “Clean Up Woman” would be memorialized when it was sampled for Mary J. Blige’s remix of “Real Love,” going down in hip-hop/soul history.
