Lost Sundays is run by Finely Tuned, the creators of Lost Paradise, a 4-day festival over New Years in Glenworth Valley. Lost Paradise started in 2013 and has grown a considerable following in the years since. On 30 May 2021, the fellas at 'Finely Tuned' events management ran their first Lost Sundays Event. Testament to their work with Lost Paradise, they sold out their first show a few weeks prior.
