Claypool also revealed that the band were "talking about going into the studio in November. But it's all a little premature – we'll see what happens".<ref name="herb back">{{cite web|title=Q&A: Les Claypool on Primus' Future and His TV Show With Dean Ween|work=Rolling Stone Magazine|author=Greg Prato|date=September 25, 2013 |url=https://www.rollingstone.com/music/news/q-a-les-claypool-on-primus-future-and-his-tv-show-with-dean-ween-20130925|access-date=September 25, 2013|archive-date=February 24, 2015|archive-url=https://web.archive.org/web/20150224020033/http://www.rollingstone.com/music/news/q-a-les-claypool-on-primus-future-and-his-tv-show-with-dean-ween-20130925|url-status=live}}</ref> In December, Alexander revealed that the band had been "in Les's studio working on stuff for the new year's show but I don't know if there are any plans for releasing that."

The first official Primus show with Alexander back on drums was New Year's Eve 2013 at the Fox Theater in Oakland. The band performed their first set in front of the iconic ''Suck On This'' backdrop seen in the "[[Too Many Puppies]]" music video. For their second set, Primus were joined by "the [[Colonel Les Claypool's Fearless Flying Frog Brigade|Frog Brigade]] Ensemble", consisting of saxophonist [[Skerik]] and percussionist [[Mike Dillon (musician)|Mike Dillon]], as they performed the soundtrack from the 1971 film ''[[Willy Wonka & the Chocolate Factory]]'' in its entirety. The band later announced that a studio recording of the soundtrack, titled ''[[Primus & the Chocolate Factory with the Fungi Ensemble]]'', would be released on October 21, 2014.<ref>{{cite web|title=Primus Wonka Album <nowiki>|</nowiki> Signs Point Towards October Release|publisher=JamBase.com|url=http://www.jambase.com/Articles/122283/Primus-Wonka-Album-Signs-Point-Towards-October-Release|date=July 24, 2014|access-date=April 22, 2015|archive-date=September 22, 2015|archive-url=https://web.archive.org/web/20150922171932/http://www.jambase.com/Articles/122283/Primus-Wonka-Album-Signs-Point-Towards-October-Release|url-status=live}}</ref>
