Was sad to hear of Alanna leaving, but I'm glad she has decided to focus on her mental health, that is obviously of much more importance than touring in a band and was a very mature choice to make on her part. I hope she continues to release her solo stuff in future though, I love her voice.
Songs like 'Sugarcrush' and 'Do You Really Wanna Know...' are most definitely twee and it's not just because of vocals. There's the jangle of the guitars, the sweetness of the melody, and a pretty clear Beat Happening and Black Tambourine influence.
they're definitely working on a sound that's been carved out before (by tweeish bands on slumberland, k records, etc) , but the riffs get so much heavier than those bands, which is pretty refreshing. also, "wussy void" might be the song of the year, sounds so good loud with the bass cranked.
