Cyndi Lauper, Rufus Wainwright and Melissa Etheridge are headlining “Rock to Win” in Denver, CO on August 26. This event will take place the second night of the Democratic National Convention, and will be held at the Fillmore Auditorium in Denver; a venue modeled after the historic San Francisco Fillmore rock club.

“Rock to Win” is presented by The Human Rights Campaign, the nation’s largest gay, lesbian, bisexual and transgender civil rights organization.

“I am thrilled that Cyndi Lauper and Rufus Wainwright will join HRC in celebrating equality at ‘Rock to Win’,” said Human Rights Campaign President Joe Solmonese in a statement. “In 2004, GLBT issues were used by the right wing in an attempt to distract and manipulate voters. ‘Rock to Win’ is a celebration of the progress our community has made in the intervening four years, and a grand kickoff to hard work ahead in the general to elect a new president of our nation.”

This summer, Lauper hit the road for the second annual True Colors Tour in partnership with the Human Rights Campaign. The tour emphasized the importance of voting and participating in 2008’s historic elections. The tour concept was conceived by Lauper stemming from her desire to give back to the GLBT community for the love and support they have given her throughout her career. Wainwright, who is openly gay, previously performed at HRC’s landmark concert series and tour Equality Rocks.
