Want One is the third studio album by the Canadian-American singer-songwriter Rufus Wainwright, released through DreamWorks Records on September 23, 2003. The album was produced by Marius de Vries and mixed by Andy Bradfield, with Lenny Waronker as the executive in charge of production. Want One spawned two singles: "I Don't Know What It Is", which peaked at number 74 on the UK Singles Chart, and "Oh What a World". The album charted in three countries, reaching number 60 on the Billboard 200, number 130 in France, and number 77 in the Netherlands. Want One features guest vocals from Martha Wainwright, Joan Wasser, Teddy Thompson and Linda Thompson, as well as a banjo solo on "14th Street" by Wainwright's mother Kate McGarrigle. For the album, Wainwright won the award for Outstanding Music Artist at the 15th GLAAD Media Awards, won Best New Recording and received a nomination for Best Songwriter at the OutMusic Awards, and was nominated for the 2004 Shortlist Music Prize. It was the first part of what was intended to be a double album called Want. The second part, Want Two, was released the following year. Want One was later repackaged along with Want Two as a two-disc set titled Want and was released on November 28, 2005 in the UK to coincide with Wainwright's tour.
