Ashford & Simpson - Stay Free (Expanded Version) (1979)

The title track was spectacular, and the rest of the album was expertly produced, performed, and arranged. Ashford & Simpson dominated the '70s as few couples ever have in any era; they were the textbook blend of classic R&B energy and urban contemporary class and sophistication. Their best material was neither so generic that it lacked soul, nor so soulful that it couldn't attract a crossover audience.
