Imagine travelling back to 1972, to a Baptist Church in Los Angeles, just in time for Aretha Franklinto deliver a performance that would go down in history. That’s what watching Amazing Grace feels like. The astonishing documentary – a lost film finally unearthed and restored – captures the moment the Queen of Soul revisited her roots. The songs she recorded at the New Temple Missionary Baptist Church became the best-selling gospel album of all time, but few knew that Academy Award-winning director Sydney Pollack was there, filming. For technical reasons, the footage was shelved and almost forgotten until after Pollack’s death – and its painstaking resurrection results in spine-tingling stuff.
