Roberta Flack & Donny Hathaway (LP)

The million-selling self-titled duet album by Roberta Flack and Donny Hathaway was the breakthrough record for Flack. Donny already enjoyed some commercial success, but their hit singles "You've Got a Friend" and "You've Lost That Lovin' Feelin'" put Roberta on the radar. The sensitive and emotional masterpiece can be seen as one of the best duet albums of all time. It was the album's third single "Where Is the Love" which dominated the US radio for almost a year, and reached the fifth spot in the Billboard Hot 100. The album itself shows a work of great depth and tenderness, with some of the most impressive vocal harmonies you'll ever hear. After the success of the album, Flack and Hathaway recorded sporadically together throughout the '70s, until Hathaway's tragic death in 1979.
