Terrell's career began as a teenager, first recording for Scepter/Wand Records,before spending nearly two years as a member of James Brown's Revue, recording for Brown's Try Me label. After a period attending college, Terrell recorded briefly for Checker Records, before signing with Motown in 1965. With Gaye, Terrell scored 7 Top 40 singles on the Billboard Hot 100, including "Ain't No Mountain High Enough" and "You're All I Need to Get By". Terrell's career was interrupted after a late 1967 concert resulted in the singer collapsing in the arms of Gaye as the two performed, later resulting in her being diagnosed with a brain tumor. Terrell would have eight unsuccessful operations before succumbing to the illness on March 16, 1970 at the age of 24.
