Mister Saturday Night and Mister Sunday are parties put on by DJs Eamon Harkin and Justin Carter. You can see the schedule and get tickets for both parties here.
Started in 2009 in DIY spaces and back yards, the parties these days happen at Nowadays, the place Justin and Eamon opened in 2015.
In addition to throwing parties and running Nowadays, Eamon and Justin run a label called Mister Saturday Night Records and produce a series called Planetarium, where people bring pillows, blankets and sleeping bags, lie in silence and listen deeply to music.
