Martha and the Vandellas (known from 1967 to 1972 as Martha Reeves and the Vandellas) were an American vocal group who found fame in the 1960s with a string of hit singles on Motown's Gordy label.
 Founded in 1957 by friends Annette Beard, Rosalind Ashford and Gloria Williams, the group eventually included Martha Reeves, who moved up in ranks as lead vocalist of the group after Williams' departure in 1962.
 The group signed with and eventually recorded all of their singles for Motown's Gordy imprint.
"I Promise to Wait My Love" is a 1968 single recorded by girl group Martha and the Vandellas, released on the Gordy label.
 The third release from the group's "Ridin' High", it was another single given to them by producer Richard Morris with co-written credit to Sylvia Moy.
 Produced under a Memphis soul sound similar to soul singer Aretha Franklin, the song has the narrator (lead singer Martha Reeves) promising to wait for her love as he fights in Vietnam, although the song does not overtly reference the war, disguising it as the war being another woman saying that she will love him "even though (he does her) wrong".
 This song was the group's first single to miss the top 40 on the pop singles chart peaking at number 62, while it netted a top 40 entry on the R&B singles chart peaking at number 36 on the chart.
"Quicksand" is a 1963 soul-dance single by Motown girl group Martha and the Vandellas.
 It was built around a similar gospel-inspired delivery of their previous release, their break-out hit, "(Love Is Like a) Heat Wave", but was slightly slower with a harder edge.
 This time, lead singer Martha Reeves explains how her loved one brings her "closer" to him explaining that his love was like "quicksand".
 Released in November 1963 on the Gordy label, the song became another Top Ten hit for Martha & the Vandellas, eventually reaching number eight on the "Billboard" Hot 100.
 It was the third hit on which the group collaborated with the famed Holland–Dozier–Holland team, who would go on to record hits with the likes of Vandellas' contemporaries, The Supremes and the Four Tops.
Natural Resources is a soul album released by Motown girl group Martha Reeves and the Vandellas in 1970 on the Gordy (Motown) label.
 The album is significant for the Vietnam War ballad "I Should Be Proud" and the slow jam, "Love Guess Who".
 The album marked a return from lead singer Martha Reeves, recovering from a time in a mental institution after an addiction to painkillers nearly wrecked her (though it still took her until 1977 to beat her addiction).
 This was the next-to-last album for the Vandellas, whose success had peaked in the mid-1960s.
