TICKETS ARE STILL AVAILABLE SATURDAY, JANUARY 11: Plymouth Church will be hosting a benefit concert for Free the Slaves. Join an all-star lineup, including The Impressions, Naomi Shelton, members of The Dap-Kings, The Gospel Queens and the Inspirational Voices of the Abyssinian Baptist Church. Plymouth Church has a long history of involvement in the abolition and civil rights movements. It was once known as “Grand Central Station” of the Underground Railroad. Abraham Lincoln attended service there. Dr. Martin Luther King Jr. preached there. The historic venue will again be filled with the sounds of freedom at the Let Freedom Ring concert.
