In a retrospective review, Bruce Eder of AllMusic wrote, "This album, the group's third, was where they showed just how far their talents extended across the musical landscape, from blues to R&B to classical rock. In contrast to their hastily recorded debut, or its successor, done to stretch their performance and composition range", calling the title track "one of the finest songs ever to come from Procol Harum and one of the best pieces of progressive rock ever heard".
