Essential Mix opened my early 2000s teenage world to so much more electronic music. Good memories of downloading sets via Napster and manually recording on to cassettes to listen to in my '95 Saturn. What a weird statement.
I would say it heavily depends on what converts and festivals you’re going to. I just went to Making Time in Philadelphia where Fourtet was the headliner and by far the biggest name. Everyone else would be what you would consider “underground” or niche. My favorite DJ, Donato Dozzy, played an incredible set.
anyways, rutracker or many of the other private trackers
