Background: Paul Duane Beauregard, (born January 12, 1977) better known by his stage name DJ Paul, is an American rapper, record producer, DJ, songwriter and entrepreneur from Memphis, Tennessee. He is a founding member of hip-hop group Three 6 Mafia and Da Mafia 6iX and the half-brother of the late rapper Lord Infamous. DJ Paul started his career in the late 1980s as a DJ and released a number of solo tapes, as well as three collaboration albums with Lord Infamous as The Serial Killaz. Juicy J was introduced and the three founded the group Three 6 Mafia, going on to achieve national success in the late 1990s and early 2000s.
Context: In 2006, DJ Paul, Juicy J, and Crunchy Black won an Academy Award for Best Original Song for "It's Hard out Here for a Pimp" from the film Hustle & Flow. The song, which they co-wrote with HCP member Frayser Boy, was also ranked at number 80 on VH1's "100 Greatest Songs of Hip Hop".  After Three 6 Mafia released their 2008 album Last 2 Walk, the group had conflicts with their label Sony about their music style, which led DJ Paul and Juicy J to pursue other ventures and their solo careers.  In 2009, Paul released The Weigh In - his first mixtape since the Volume series in the early 1990s. A few months later he followed up with his second solo album Scale-A-Ton, released under Paul's newly founded label Scale-A-Ton Entertainment. The album was received well by critics, earning a positive review and an "Album pick" by AllMusic. In 2010, Paul released his second mixtape Too Kill Again, hosted by DJ Scream and DJ Whoo Kid. The mixtape features many upcoming and new Memphis artists such as Lion Heart, Thug Therapy, Partee and Miscellaneous. DJ Paul stated the tape was a preview to his upcoming album, also titled Too Kill Again, which however was never released. Instead, in 2011, Paul made a new collaboration mixtape with rapper Ya Boy and producer Lil Lody, called Pray For Forgiveness. A few months later Paul released a retail No-DJ version with bonus songs to iTunes.  In 2012, Paul announced he was working on an experimental dub-hop EP called A Person of Interest. Later he changed it into a full featured album, which was released on October 22. A Person of Interest was packed with a bonus DVD, including a self-titled short movie, music videos and behind the scenes footage. Paul released videos for a number of songs from the album, including "What I Look Like (W.I.L.L.)", "Wit Tha Shit", "Trap Back Jumpin", "E&J" and a remix of "I'm Dat Raw" with Snow Tha Product. Paul called A Person of Interest his favorite solo album, stating that he loved the production and the "raw" sound of the album.
