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.
>Electronic music is anything but niche
Electronic music is a huge genre. There's a ton of popular artists but there's also so much great stuff you'll never hear at concerts/festivals.
