Step 1 : Introduction to the question "U2's "Angel of Harlem" was written about what singer?"
"Angel of Harlem" is a song by Irish rock band U2. "Angel of Harlem" was written about Billie Holiday, a Jazz singer who moved to Harlem as a teenager in 1928. Nicknamed "Lady Day”, Billie Holiday was one of the most influential jazz singers of all time. Her final years, however, were tragic. She became addicted to heroin, was swindled out of her earnings, and died of cirrhosis of the liver at age 44 with only $0.70 in the bank. She was arrested on her deathbed, in 1959, as narcotic addiction at that time was considered a crime, not an illness.
