Songwriting and production team Ashford & Simpson are responsible for hits by soul superstars such as Ray Charles, Marvin Gaye, and Aretha Franklin, penning the classics “Ain’t No Mountain High Enough,” “Let’s Go Get Stoned,” and “Ain’t Nothing Like the Real Thing,” among others. But Ashford & Simpson were recording stars in their own right, with a discography that stretches from the early 1960s to the 2000s.
