Following departure from the Supremes in 1970, Ross embarked on a highly successful, globally ground-breaking solo career in music, television, film and stage. Ross' eponymous debut solo album that same year, featured the U.S. number-one hit "Ain't No Mountain High Enough" and music anthem "Reach Out and Touch (Somebody's Hand)". It was followed with her second solo album, "Everything Is Everything", which spawned her first UK number-one single "I'm Still Waiting". She continued her successful solo career by mounting elaborate record-setting world-wide concert tours, starring in a number of highly watched prime-time television specials and releasing hit albums like "Touch Me in the Morning" (1973), "Mahogany" (1975) and "Diana Ross" (1976) and their number-one hit singles, "Touch Me in the Morning", "Theme from Mahogany" and "Love Hangover", respectively. Ross further released numerous top-ten hits into the 1970s, 80s and 90s. She achieved two more US number-one singles, "Upside Down" (1980) and "Endless Love" (1981), as well as UK number-one hit "Chain Reaction" (1986) and UK number-two hit "When You Tell Me You Love Me" (1991). In 2019, Ross made history by charting four more number-ones on the U.S. "Billboard" Dance Chart in just two years with remixes 'Ain't No Mountain High Enough 2017' in January 2018, 'I'm Coming Out/Upside Down 2018' in August that year and 'The Boss 2019' in April 2019.
