<human>: In early 2013, DJ Paul focused on performing as a DJ, and created a DJ duo, called S.I.M. (Sex is Mandatory). The group created a number of live sets, as well as remixes to songs, such as Just Blaze & Baauer's "Higher".  In late 2013, Paul and Lord Infamous were discussing creating a sequel to their 1993 album Come with Me 2 Hell, when the latter came with the idea to try and reunite the whole Three 6 Mafia crew. Infamous brought back Crunchy Black, Koopsta Knicca and Gangsta Boo, and the five of them reunited as "Da Mafia 6ix" with plans to release an album in 2014. On November 12, 2013, Da Mafia 6ix released their first mixtape 6ix Commandments. The tape was almost entirely produced by DJ Paul and featured Yelawolf, 8Ball & MJG, Krayzie Bone, Bizzy Bone, SpaceGhostPurrp and HCP affiliates Lil Wyte, Skinny Pimp and La Chat, among others. Juicy J and Project Pat also appeared as surprise guests on the posse song "Body Parts", being credited just as "& more" in the track listing.  DJ Paul collaborated on a mixtape titled Clash Of Da Titans with fellow Memphis producer Drumma Boy that was released on October 23, 2013, and on a free EP, called Black Fall, with rapper Yellawolf, which they put out for Halloween on October 31, 2013. On November 26, 2013, DJ Paul released Volume 16: The Original Masters, a remaster of his 1994 mixtape 4 Da Summer of '94. It was revealed on the PSYR17 EP given away at the 2014 Gathering Of The Juggalos that DJ Paul plans to release his next solo album "Master Of Evil" on Psychopathic Records in 2015. He later confirmed it himself on the 28th of August on The Australia underground hip hop podcast "The Underground Podcast", as well as on the outro song to The Killjoy Club's debut album "Reindeer Games".  DJ Paul has been announced to play South by Southwest showcase in Austin, Texas on March 21, 2015.  On August 19, 2016 DJ Paul announced that he has signed to Yelawolf's Slumerican Records.
