In October 2013, Marshall joined a temporary supergroup called "Salvador Dalí Parton" with fellow Musicians Gill Landry of Old Crow Medicine Show, Mike Harris of Apache Relay, Jake Orrall of JEFF the Brotherhood, and Justin Hayward-Young of the Vaccines. The band, intended as a joke from the start, wrote six songs in 20 minutes on their first day together, held its one and only full-band rehearsal the next day, and performed six shows around Nashville, Tennessee, the following night before breaking up.
In 2015, Marshall became interested in techno music and electronic dance music after spending several nights attending James Ford residency in a night club. In 2016, he joined the Austrian DJ duo HVOB for a collaboration; they recorded an album named Silk. Their first single, called "The Blame Game", was released in February 2017. The album was released on March 24. They toured across Europe and Asia, playing in festivals and night clubs while Winston was also performing in concerts with Mumford & Sons.
