Dillard returned to play songs from Mangled Demos live with Buzz Osborne and Dale Crover (on bass) under the name "Melvins 1983" starting in 2008. They collectively played  a few shows, including two shows to celebrate Jello Biafra's 50th birthday and an appearance at the ATP "Nightmare Before Christmas" festival later that year. The Melvins 1983 lineup also performed for the first of three sets on the bands 25th Anniversary tour in 2009 and on one of the Endless Residency sets at the Spaceland venue in Los Angeles in 2011.
Dillard also plays drums on Tres Cabrones, making his first recordings with the Melvins in 29 years. The majority of the songs included on the album had been released in a variety of limited edition EPs, singles and compilations, primarily through Amphetamine Reptile Records, starting in 2012 before Tres Cabrones came out one year later.
In September 2015, the Melvins 1983 released the Beer Hippy EP on AmRep. All four tracks from the EP were included on Basses Loaded, released by Ipecac Recordings in June 2016.
