The National, fun. and Rufus Wainwright are among the acts that have signed on to perform at Freedom to Love Now!, an Oct. 30 benefit concert lined up at New York City's Beacon Theatre that will raise money for the marriage equality organization Freedom to Marry.

Tickets to the event, which is being organized by the BOOM for Equality initiative, went on sale Saturday and are currently available for purchase online here. There are three different levels of tickets available, ranging in price from $45 to $150 for general admission seats to $1,200 for VIP packages, which include passes to dress rehearsal, invitations to a meet-and-greet party and more.

Other acts confirmed for the show include Brooklyn alt-rockers They Might Be Giants, blues singer Toshi Reagon and cabaret star Mx Justin Vivian Bond, with more to be announced. The event is co-organized by Thomas Bartlett, the music director and curator for Freedom To Love Now! and a pianist who has toured with Antony and the Johnsons, Martha Wainwright and others.

"The key to winning the freedom to marry is raising our voices, opening hearts, and moving minds -- and how sweet and powerful when we do all that through music," says Freedom to Marry founder Evan Wolfson in a press release. "[We are] happy to be a part of the Freedom to Love concert and to support such a diverse, talented group of performers who are giving their talent and time to this important cause."
