the playing in general is excellent. the singing is good. the atmospherics are terrific.
the composition is very good. nice deployment of the key-change-for-mid-song-solo strategy.
hooray for bassists who know how to do something other than play the 1-5.
it doesn't sound derivative
putting my producer hat on:
the bass drum is kind of too busy, especially in the quiet parts; the combination of the kick and the bass guitar gets muddy when things get loud. i hate to say it should be changed, though, because it has a kind of New Orleans feel that adds to the atmo. if you were trying to perfect things, it could probably be fixed in the mix with a combination of tweaking the volume and position of the kick drum hits and/or the frequencies of the bass and kick.
it would probably sound really cool if you harmonized in an angular kind of X or Jefferson Airplane style...not so consonant as shoegaze, y'know? with your vocal timbres it would sound especially boss with the female vox singing the low part.
for my taste, the chorus could have repeated longer at the end before it quieted down. but then, i'm an old stoner and like my spacy shit loooooooong.
it sounds like it's overloading somewhere around 6000-8000 Hz in the mix when all the fuzz is happening, with the combination of the multiple fuzzes and the loud cymbals. if this is a deliberate stylistic decision on your part, ignore this comment.
the thing is, it doesn't sound like something people came up with fucking around...it sounds like a group.
