Kind of a psych-folk band: The Adventures of the Silver Spacemen Punk, somewhat along the lines of what you posted: Miami Doritos Awesome, dirty surf band: Harmonica Lewinsky Sad, lo-fi and new wave influenced: Bad Cello
I'm loving Miami Doritos. They make me think you might like SKATERS. They're a bit of a garage rock band but they got some really good songs. A little bit on the romanticized kind of way, not love per se but life views in general. In case you might have missed it, PUP really blew up on some of the smaller music subreddits. They actually remind me a bit of Against Me! before they went down the dark path of selling out. A band that I tell everyone who will even listen to me about is The Diminished Men. They're a psychedelic band with a touch of surf rock and a western sound. They blew me away live.
I'm a big fan of SKATERS and PUP, I haven't heard The Diminished Men before but I'm checking them out right now and am really liking it, thanks for bringing them up.
