Gospel music never had a more dynamic singer or fiery figure than Mahalia Jackson, and this lavish collection offers a double helping of her most closely identified songs, the bulk of them recorded in the ’50s and ’60s. This is the place to hear Mahalia do what she does best, wringing every ounce of praise and passion from standards like “Didn’t It Rain,” “If I Could Hear My Mother Pray Again,” and “Keep Your Hand on the Plow.”
