Mountain High... Valley Low is the sixth studio album by American singer Yolanda Adams. It was released by Elektra Records on September 3, 1999, in the United States. The album stands as Adams's best-selling to date, having sold 1,374,000, as of 2009, and is certified platinum by the Recording Industry Association of America (RIAA). The album won the Grammy Award for Best Contemporary Soul Gospel Album and remains one of the best-selling gospel albums of all time.
Several singles were released from Mountain High... Valley Low. The set leads with the Warryn Campbell-produced "Yeah", which was co-written by gospel duo Mary Mary who springboarded from the song to gain their own fame. The most notable single was the second release, "Open My Heart," which became a massive crossover fixture on R&B radio. Both of the singles had accompanying music videos. Remixers like Maurice Joshua, Digital Black-N-Groove, Pound Boys, and Junior Vasquez were brought in to turn both of these songs into dance club-friendly material. "The Things We Do" and "Fragile Heart" were also serviced to radio and fared well on adult contemporary stations.
