“Listen to this track by Motown titan and smooth as silk soul-pop provider Marvin Gaye, along with his vocal counterbalance, and no slouch in the soaring vocal department herself, Tammi Terrell,” (The Delete Bin). “It’s ‘Ain’t No Mountain High Enough,’ a single from writing partnership and real-life couple Ashford & Simpson. The song was a top twenty hit single in 1967, released on the Tamla label, a sister label of Motown, eventually appearing on the Marvin Gaye/Tammi Terrell joint album United.
The song was thought of by its writers as being their golden ticket into the Motown stable, even turning down Dusty Springfield who wanted to record it herself. Ashford and Simpson held it back , and it was eventually offered as a duet to Marvin Gaye, and to Tammi Terrell who made it one of the most prominent songs of the Motown catalogue, and an important record of the whole decade. Later on, Diana Ross would record it when she split with the Supremes and went solo in 1970. It would be a number one hit, and become a signature tune for her.Yet, it’s the alchemy that the Gaye-Terrell version offers that makes this the definitive version of the song.
… Their collaboration yielded several hits of the classic Motown era, including ‘Ain’t Nothing Like The Real Thing,’ ‘You’re All I Need To Get By,’ and ‘Your Precious Love,’ also all Ashford & Simpson songs. They would record three albums together over the next two years, with this period being looked upon by many as one of the finest in Marvin Gaye’s career, with Terell contributing significantly to that success.
But, there was something very wrong. Terrell had suffered migraines for many years, and one night during a concert in Virginia, Terrell stumbled on stage and collapsed in Gaye’s arms … Later, it was discovered that she was suffering from malignant tumours in her brain.” No treatments were successful in the long term, and “Tammi Terrell died in March of 1970 at the young age of 24, the same year Diana Ross recorded her version of this song. Retrospectively, ‘Ain’t No Mountain High Enough’ is an anthem to Terrell’s determination to succeed despite her cancer diagnosis … The song’s epic quality would attract cover versions from many. But, this original version is the one by which all others must be judged, including Diana Ross’, largely due to the sheer defiant vitality that Tammi Terrell brought to the performance. Marvin Gaye would of course continue to make his mark as one of the most gifted vocalists of his generation. But with Terrell gone, this vital phase of his career was at an end, with that combination of voices bursting with personality never to be repeated.”
Packing a complex arrangement and a true wall of sound into its spare 2.5-minute length, the track climbs to its bridge at 1:18, then shifts up from D major to Eb major at 1:37.
