(AllHipHop News) The wait for Outkast rapper Big Bois solo debut album Sir Lucious Leftfoot: The Son of Chico Dusty, as well as a new album from the Atlanta-based duo is coming to end. The 14-track Def Jam Recordings offering, which features appearances from T.I., Sleepy Brown and Jamie Foxx, will hit stores on July 6. Producers for the album include Scott Storch, Boi-1da, Organized Noize, Andre 3000 and Lil Jon, among others. The release of Sir Lucious comes amid a string of delays that raised doubts about the project. Despite the release of four singles (the 3000 and Raekwon-assisted Royal Flush, Sumthins Gotta Give featuring Mary J. Blige, Ringtone and Dubbz) and leaked collaborations with 3000 and Brown (Looking for You), George Clinton and Too Short (Fo Yo Sorrows), Gucci Mane (Shine Blockas) and T.I. (Tambourine), Sir Lucious was never made available to the public. Shortly after the album summer release, Big Boi will appear at the Pitchfork Music Festival. The event, will take place during the July 16-18 weekend in Union Park in Chicago. In addition to Sir Lucious, plans to unleash the follow-up to Outkast s 2006 opus, the soundtrack to the film Idlewid, will resume. Big Boi confirmed to Billboard.com that the long-awaited album will be released after Sir Lucious.
