Tonight, the Rock and Roll Hall of Fame opens an exhibit dedicated to the women who have played a significant role in the history of music over the years. It's called Women Who Rock: Vision, Passion, Power.

The exhibit features pieces from classic female rock-and-rollers like Wanda Jackson, Ma Rainey, Bessie Smith, as well as more contemporary acts like Lady Gaga, Britney Spears, Madonna, and Christina Aguilera.

The idea was brought up after Cyndi Lauper paid a visit to the Rock and Roll Hall of Fame and claimed it was too male-dominated. Other important figures shared the same feelings with Ms. Lauper. "Women were the subjects of songs. They were the objects of affection. But they appeared in the audience and not on the stage," stated Glenn Altschuler, author of All Shook Up: How Rock n' Roll Changed America.

The exhibit opens tonight at the on the museum's fifth and sixth floors. Visit the official page for more information.
