earlier records which had mixed black singers with a white pop sound had sold well, by 1966 the black political movement was encouraging African Americans to take a pride in their own culture, and "River Deep – Mountain High" was out of step with that movement. The single, released on London Records in Europe, was a hit overseas. It peaked at No. 3 in the UK, No. 9 in the Netherlands, and it reached No. 1 in Spain. George Harrison praised the record, declaring it "a perfect record from start to finish. You couldn't improve on it." Reissues After "River Deep – Mountain High" was revived by other bands, Ike & Tina Turner's original version was reissued by A&M Records in 1969. It has since gained the recognition Spector wanted for the record. Reviewing the single, Record World called it a "classic, perhaps the greatest single of all time." Ike & Tina Turner recorded different renditions of the song without Spector's "Wall of Sound" production style. A version on the 1973 album Nutbush City Limits was released as a single titled "River Deep, Mountain High 1974" on United Artists Records in France. Another version from an undetermined year was released on the 1991 compilation Proud Mary: The Best of Ike & Tina Turner. Tina Turner recorded a few solo versions, in 1986, 1991 and 1993. Tina included live performances on her albums, Tina Live in Europe and Tina Live. Chart performance Certifications The Supremes and the Four Tops version In 1970, their post-Diana Ross era, The Supremes and the Four Tops released a version. Produced by Nickolas Ashford and Valerie Simpson, the single was one of several recordings that paired the two Motown groups. The Supremes and Four Tops cover, included on the 1970 LP The Magnificent 7, with its soaring vocals and string section, peaked at No. 7 on the soul chart and No. 14 on the Billboard Hot 100 in 1971, making it the highest-charting version of the song in the United States. Their version also peaked No. 11 on the UK Singles Chart, No. 23 in Belgium, and No. 25 on Netherlands' MegaCharts.
