Dar Williams and Joan Osborne will join forces and make a stop on their fall tour in Milwaukee. The two female singer-songwriters will play at Historic Turner Ballroom on Tuesday, Sept. 27.

Tickets go on sale Friday, July 29 at noon. The cost is $25.

Both artists played the inaugural Lillith Fair tour in 1997.

They will perform their own material, as well as each other's, along with some "musical surprises." This is the first time the duo will perform together.

Following the tour, Williams will head for the studio to record her eighth album. Osborne, best known for her 1995 hit, "One Of Us," will continue working with her new band, Trigger Happy, which features two former members of the Black Crowes.
