Canadian singer-pianist Rufus Wainwright [ tickets ] is providing a peek of his forthcoming album, "Poses" (DreamWorks), with a three-week tour that is slated to open in early May.

Wainwright, the son of folk singer Loudon Wainwright III, has tapped Vancouver’s Tegan and Sara to open the shows. The 20-year-old twin sisters released their debut, "This Business of Art" (Vapor), in August.

"Poses," due to hit stores on June 5, was produced by Pierre Marchand (who also turned the knobs for Wainwright’s self-titled debut), Alex Gifford (of the electronic duo Propellerheads), Ethan Johns (Emmylou Harris, Whiskeytown) and contemporary composer Damian le Gassick. Guest performers included bassist Melissa auf Der Maur (Hole, Smashing Pumpkins), singer-songwriter Teddy Thompson, eels drummer Butch and Wainwright’s sister, Martha Wainwright.

On "Poses," Wainwright covers his father’s song "One Man Guy."
