Dionne & Friends refers to the collaborative project of American singer Dionne Warwick and her contemporaries. The project is best known for the hit single "That's What Friends Are For" featuring Gladys Knight, Elton John, and Stevie Wonder, which topped the Billboard Hot 100 in 1986. Their music style combines elements of pop, R&B, and adult contemporary. The collaboration's significance lies in its charitable impact, as proceeds from their hit single were donated to AIDS research, marking an important early contribution to the cause in the music industry.
