What is the most influential soul album in history?

Amazing Grace

Aretha Franklin's 1972 gospel-soul live album reconnected soul music to its church roots and became the best-selling live gospel album ever, influencing every gospel-soul singer since.

Curtis

Curtis Mayfield's 1970 self-titled album established the template for socially conscious soul — funky, lyrically searching, and instrumentally innovative in ways that predicted both disco and hip-hop.
