On May 13 the museum will open the "Women Who Rock: Vision, Passion, Power" exhibit, featuring images and artifacts from Joan Jett, Ma Rainey, Joni Mitchell, Lady Gaga and more.
Lady Gaga inspires everyone, including other female pop stars to be elusive about their sexuality; out lesbians participate in Lilith Fair; and four established singers come out.
The English singer talks about her hatred for homophobia, how she's had feelings for women and why Kathleen Hanna and Sleater-Kinney are her biggest influences.
