The only way to hear soul is from a real, bona fide soul sister. Luckily, Mavis Staples is in the building. It’s her 75th birthday concert, and she’s looking back on on her influential hits. With her band The Staple Singers, she recorded protest songs for the American civil rights movement and produced hit after hit. Never one to slack, she’s now back with her solo material. See a legend at work. Over 18s only.
