Sorry it took me a couple days to answer this! First, I must tell you that I love teen suicide, but had never heard of pill friends, so now I have more awesome music to listen to, which I always appreciate. Second, I highly recommend the blog Chug Life, which, while not a queer focused blog AT ALL, has a lot of really great lo-fi music of all sorts of genres, although there is a big emphasis on screamo/skramz and its many derivatives. That’s where I first found teen suicide, and a bunch of other bands I like that aren’t queer (as far as I know), like The Pine and My Dad (both of whom you’d probably really enjoy if you like teen suicide), Innards, and The Sky Above and Earth Below.
But anyways! Queer bands in that vein-ish, kinda maybe, I gotta admit I tend to err more on the pop-punk side of things, so I may be personally biased in my recommendations: Filthy Liars (acoustic Canadian emo-ish feelings! Also, go down the rabbit hole of their recommendations, there’s a whole awesome Halifax queer punk scene going on that’s well worth your time), Shady Hawkins (definitely more garage punk than anything, and harder than the stuff you mentioned liking, but they have a lo-fi vibe and are fucking awesome), Aye Nako (they’re pop-punk, and so good), Dogjaw (should be right up your alley, lots of trade off female shouting vocals, dirty guitars and trebely bass, plus they put on a great live show), Little Waist (again, more pop-punk-y, but front woman Audrey Zee has released some acoustic tracks on their bandcamp as well, which might be more your speed).
I hope that’s a good start! Please write back if i got all of these wrong and you’re looking for something different. Followers, reblog this with any recommendations you may have! More awesome music for everyone!
