The collaborative project between Diplo and Mark Ronson is set to officially launch soon according to Diplo. Silk City (or the idea of it) was first mentioned by him in an interview published last August. The interview took place in April 2017: Hopefully this actually happens. I’m still waiting for the Mark Ronson x Kevin Parker x SZA album to get finished. Diplo and Mark will be playing their first show as Silk City at the Governers Ball in June, so I imagine we should be hearing more around then.
