In spring 1970, after the Top 20 success of her first solo single, "Reach Out and Touch (Somebody's Hand)", Ashford and Simpson had Ross re-record "Ain't No Mountain High Enough". Initially, Ross was apprehensive, but was convinced to make the recording. The remake was a complete reworking of the song, featuring a style similar to gospel with elements of classical music strings and horns, and spoken word passages from Ross. The Andantes, Jimmy Beavers, Jo Armstead, Ashford & Simpson and Brenda Evans and Billie Calvin of the Undisputed Truth were used as backing singers, giving the song a soul and gospel vocal element. Ross' version of the song was released on July 19, 1970 as the second and final single from her solo self-titled 1970 debut album by Motown.
