Damita Jo is the eighth studio album by American singer Janet Jackson. It was released on March 30, 2004, by Virgin Records. The album takes its title from Jackson's middle name. Its music incorporates pop rock, electro, house, and hip hop styles, in addition to R&B. Its concept is based on Jackson's alternate personalities, exploring themes involving intimacy, monogamy, love, and dance. Its production is derived from producers including Dallas Austin, Scott Storch, BAG & Arnthor, Arnthor Birgisson, Rich Harrison, Télépopmusik, Just Blaze, and Kanye West; in addition to Jackson and Jam & Lewis. The album was recorded over 18 months, the longest span of time Jackson had spent on a project. Jackson sought to find producers who identified with her emotions, intending "hard-hitting dance music". Producers declared it "a really sexy record" which was bold, fun, and positive. Multiple personae portrayed include the obstinate "Damita Jo" and lascivious "Strawberry Bounce". Jackson stated that they were "another way to express and expose a deeper part of me", comparing her writing process to that of a novelist; inventing characters with independent personalities. Jackson claimed that the aforementioned characters "absolutely" live inside of her, stating it "feels wonderful" to release them. Prior to its completion, Jackson performed a medley of hits at the Super Bowl XXXVIII halftime show. The performance ended in Jackson's breast being exposed by surprise guest Justin Timberlake.
