The official trailer for Aretha Franklin's upcoming documentary, Amazing Grace, is here, and you might want to have a box of tissues nearby for this one. The film centers around Franklin's unforgettable 1972 performance of "Amazing Grace" [1] at the New Missionary Baptist Church in Los Angeles. The trailer features Franklin standing behind the pulpit as she begins to sing with remarkable authority and stage presence [2]. Although Franklin was just 29 years old at the time [3], she was able to stir everyone in the congregation with her stunning vocals. [4] The clips were shot by Sydney Pollack and compiled by Alan Elliott.

That same day at the church, the late and great [5] Franklin also belted other songs, including "Mary, Don't You Weep" and "Climbing Higher Mountains." The show was then turned into the 1972 soundtrack Amazing Grace, which is still the best-selling live gospel album [6] of all time. And up until recently, the footage of that performance was unreleased. So get ready to go to church when the documentary hits theaters on April 5!
