Follow artist socials, they will promote themselves at gigs. Search for your town name + edm genre on soundcloud, that may tell you the names of regular festivals,events and club nights from the set names. Follow said venue's socials, or regularly check their website for upcoming events.
Figure out who your local promoters are, & follow their socials also.
Go to a youth focused cafe or skate park, look at what event posters are being posted on the walls? Unsure if the kiddies still post bills for small events, honestly everything is on social media these days, and is where you should start once you've identified some names.
In my city, facebook is the most reliable way to discover events - we have very active promoters in the main '$city $genre scene' public fb groups.
In Seattle at least they do posters. Mostly in Cap Hill (the gay area). The super small stuff is generally social only but anything with an actual venue will pop up. 19hz is also a good resource, it's searchable and city specific.
I've not found that to be the case, though I'm only casually interested these days (too old to feel comfortable at most events, worried I'm more there to relive the good old days than a 'genuine' interest etc).
With dB festival gone, do people just hit up showbox or monkey loft shows and try to make friends?
19hz has a good listing of events. A lot of it is announced on Instagram or Telegram (or the old classic of looking at the fliers on the telephone poles of cap hill). Renegades still happen (the bridge has been a super popular spot) but that season is sorta over. I more favor the Kremwork (that's more my scene) or digital hardcore shows which seem to just pop up everywhere.
Awesome stuff thanks, as to kremwork I wasn't aware they'd survived little marias closing - glad to hear some culture is left in the city. Funny to hear of it via HN but hey small world.
