When Janet Jackson entered the Rock and Roll Hall of Fame’s class of 2019 in March, she closed her acceptance speech with a simple request: “Rock and Roll Hall of Fame, please, 2020: Induct more women.”
The Hall has always been slow to induct women, even relative to the fairly male-dominated field of rock history. The inaugural inductions in 1986 were all men, and the next year, only one woman was inducted. Since then, only one or two women or groups including women have been inducted each year.
